How long will it take to fly from earth to the end of the universe
 
03:43
Special Thanks to: Izak Smit for the Music If you fly at the speed of light you will go around the earth 7.5 times in one second. If we maintain that same speed we can get to the moon in 1.3 seconds, and then we can go all the way to Mars in 4.2 minutes, just enough time to make some noodles and if you are fast a cup of tea. And if we carry on through the asteroid belt maintaining our speed of 300 000 km per second we will reach the gas giant Jupiter in about 43 minutes, more than enough time to eat noodles drink tea and to play a few games of black jack. From here it will take us another 86min to get to Saturn, just enough time to watch the movie shrek. To fly from earth to the end of our solar system past pluto will take 4.5 Hours at the speed of light. That’s enough time to watch fellow ship of the ring and the two towers. We maintain this speed and it takes us 4 years to get to the closest star. 4 birthdays and 4 Christmas dinners, think of a job or something you have done every day for 4 years to get perspective of your time onboard this space ship. If we want to fly from the one end of the galaxy to the other end it would take 100 000 years, that means if people on this space ship grow to the age of 100 our flight time will take 1000 generations of people getting born and growing old on board this ship before we reach our destination. Finally we reach the end of our milky way after 100 000 years of flying at incredible speeds To get us to the next galaxy we have to fly for 2.5 million years at this speed we have to wait for another 25 thousand generations to come and go before we reach our destination. Now we will attempt our journey to the edge of the universe which will take 46 billion light years, so we will go through four hundred and sixty million generations of 100 year old people before we get there, at which point we could possibly discover a multiverse. Astronomers estfimate that the observable universe has more than 100 billion galaxies. Our own Milky Way is home to around 300 billion stars. There are more stars in our universe than grains of sand on all the beaches in the world and 75% of the stars in our galaxy have planets around them, and many are in the habital zone. Considering that a teaspoon of sand has more atoms than all the stars in the observable universe just imagine all the spontaneous chemical reactions happening with all the chemicals on all the planets surrounding all the stars and then consider that the building blocks for life such as amino acids and proteins can spontaneously form in certain environments, then one has to consider the possibility that life on other planets is mathematically inevitable.

Milky Way Versus Andromeda As Seen from Earth
 
03:53
From HubbleCast. Scientists have been using Hubble observations to predict the future of the Andromeda Galaxy and the Milky Way, and how the collision will look from Earth. Projecting the motion of Andromeda's stars over the next 8 billion years, the astronomers now know the path that galaxy is taking through space. And it's heading straight for us! Computer simulations based on Hubble observations show how the two galaxies will crash together in around 4 billion years' time. The Andromeda Galaxy, some 2.2 million light-years away, is the closest spiral galaxy to our home, the Milky Way. For around a century, astronomers have known it is moving towards us, but whether or not the two galaxies would actually collide, or simply fly past each other, remained unclear. Now, a team of astronomers has used the Hubble Space Telescope to shed light on this question, by looking at the motion stars in the Andromeda Galaxy. We wanted to figure out how Andromeda was moving through space. So in order to do that we measured the location of the Andromeda stars relative to the background galaxies. In 2002 they were in one place, and in 2010 they were in a slightly different place. And that allowed us to measure the motion over a period of eight years. The motion is actually incredibly subtle, and not obvious to the human eye, even when looking at Hubble's sharp images. However, sophisticated image analysis revealed tiny movements that the scientists were able to project into the future. Based on these findings, it is finally possible to show what will happen to the Milky Way over the next eight billion years, as the galaxies drift closer, then collide and gradually merge into a single, larger, elliptical galaxy with reddish stars. And yet the Solar System should in fact survive this huge crash. The reason we think that our Solar System will not be much affected by this collision between the Milky Way and Andromeda is that galaxies are mostly empty space. Even though our galaxy, as well as the Andromeda Galaxy, has a hundred billion stars in it, they are very far apart. So if two galaxies actually collide with each other, the stars basically pass right between each other and the chance of two stars directly hitting each other is really, really small. So the likelihood that our Solar System will be directly impacted by another star, for example, in Andromeda as we collide with it is really, really small. Well, if life is still present on Earth when this happens, the changes in the sky will be quite spectacular. Now they will be very very slow because the timescales on the scales of galaxies in the Universe are very very long. So you have to think, millions of years but even then over these timescales over millions of years, we will see big changes. If we wait a few billion years, Andromeda will be huge on the sky. It will be as big as our Milky Way because we'll be very close to it. And then later, when the galaxies merge, the merged remnant of the Milky Way Galaxy and Andromeda will look more like an elliptical galaxy and we'll be sitting right in it. So the view of the Milky Way on the night sky will be completely gone and this band of light will be replaced by a more spheroidal distribution of light. And so, the Sun, born in the Milky Way almost 5 billion years ago will end its life in a new orbit, as part of a new galaxy.

10 STRONGEST Signs of Aliens and Alien Life
 
13:50
Are we alone? It’s a question that many hope to have answered, and some believe they already have the answer to. Some scientists maintain that we will find alien life in the next thirty years, if not sooner. Subscribe for more! ► http://bit.ly/BeAmazedSubscribe ◄ Stay updated ► http://bit.ly/BeAmazedFacebook https://twitter.com/BeAmazedVideos ◄ Get in touch or join the team: http://goo.gl/forms/2lOZyOeL3N SPOILER ALERT!!! A condensed list is below: ➢ 10. Tiny Life on Meteorites Earth has been hit by a number of meteoritesover the past four billion years. Of the many tons of cosmic dust and meteorites that hit the Earth on a daily basis, three have been determined to have possibly come in contact with life. Credit: http://fur.ly/0/tinylifeonmeteorites ➢ 9. The Wow Signal In 1977 Ohio State University picked up a strange signal from their Big Ear Telescope an observatory that scanned the sky for alien radio signals. On August 15, , The telescope picked up a radio signal that measured as ‘6EQUJ5’ from an area of empty space and astronomer, Dr. Jerry R. Ehman wrote the simple phrase,‘Wow’. Credit: http://fur.ly/0/thewowsignal ➢ 8. The black knight The black knight is a mysterious, unidentified satellite that was detected way back in 1899 by the brilliant Serbian inventor, Nikola Tesla, who some think intercepted signals from the unknown satellite. The satellite is believed to be 13000 years old and numerous others have since claimed to have picked up similar signals relating to its existence. Credit: http://fur.ly/0/theblackknight ➢ 7. Nasa Cover-ups If anybody in the world currently knows whether alien life exists, it would most likely be US government agencies such as NASA. What's unnerving is that there ARE many strange signs to suggest that NASA has been concealing information from the public. Credit: http://fur.ly/0/nasacoverups https://www.flickr.com/photos/gsfc/6816499986 ➢ 6. Ancient evidence Peculiar ancient hieroglyphs may be proof that even generations before us knew that alien life exists. Some famous hieroglyphics bears symbols resembling modern day vehicles, suggesting alien life was known about during ancient times. Credit: http://fur.ly/0/ancientevidense ➢ 5. Strange radio bursts Since 2001 telescopes around the world have been picking up so-called fast radio bursts that lasts just a few milliseconds and erupt with about as much energy as the sun releases in a month. Ten have been detected so far and were determined to have originated 5.5 billion light years away. Credit: http://fur.ly/0/strangeradiobursts ➢ 4. Life on Mars For more than a century, people have speculated about whether there is life on the red planet that is Mars. Thanks to NASAs curiosity rover that landed on the planet in 2012, it's likely that soon we may know whether life was or is present on the planet. Credit: http://fur.ly/0/lifeonmars ➢ 3.Life Can Exist Anywhere, Even Deep-Space Extremophiles are creatures that exist in conditions that would kill most other kinds of life. Since the building blocks of life can form anywhere, life beyond our own rock is possible and likely. Credit: http://fur.ly/0/lifeexistsanywhere ➢ 2. There are Thousands of Exoplanets In 2009 NASA launched the Kepler satellite observatory to look out into the farthest reaches of space. As Kepler scans the void, it has discovered and is still discovering, a staggering amount of exoplanets that may be habitable. In other words, our galaxy alone is full of planets within the important habitable zone, where alien life is likely to thrive. Credit: http://fur.ly/0/thousandsofexoplanets ➢ 1. Life could be in Our Backyard For life, as we know it, to survive we requires liquid water and heat. The prospect for finding liquid water within our solar system outside of earth may not be as unlikely as we first thought. Apparently there are entire oceans of liquid water beneath the crust of ice on Jupiter’s moons Europa, Ganymede and Saturn’s moon, Enceladus.

Why Is Andromeda Coming Towards Us? If Everything is Expanding Away From Each Other

I don't want to alarm you, but there's a massive galaxy heading our way and will collide with us in a few billion years. But aren't most galaxies speeding away?

Naw, I’m just kidding. I totally want to freak you out. The Andromeda galaxy is going to slam head first into the Milky Way like it doesn't even have its eyes on the road. This collision will tear the structure of our galaxy apart. The two galaxies will coalesce into a new, larger elliptical galaxy, and nothing will ever be the same again, including your insurance premiums. There’s absolutely nothing we can do about it. It’s like those “don’t text and drive commercials” where they stop time and people get out and have a conversation about their babies and make it clear that selfish murderous teenagers are really ruining everything for all of us all the time. And now that we know disaster is inbound, all we can do is ask WHY? Why this is even happening? Isn't the Universe expanding, with galaxies speeding away from us in all directions? Shouldn't Andromeda be getting further away, and not closer? What the hay, man! Here’s the thing, the vast majority of galaxies are traveling away from us at tremendous speed. This was the big discovery by Edwin Hubble in 1929. The further away a galaxy is, the faster it’s moving away from us. The most recent calculation by NASA in 2013 put this amount at 70.4 kilometers per second per megaparsec. At a billion light-years away, the expansion of the Universe is carrying galaxies away from us at 22,000 km/s, or about 7% of the speed of light. At 100 million light-years away, that speed is only 2,200 km/s. Which actually doesn't seem like all that much. Is that like Millenium Falcon fast or starship Enterprise Warp 10 fast? Andromeda is only 2.5 million light-years away. Which means that the expansion of the Universe is carrying it away at only 60 kilometers per second. This is clearly not fast enough for our purposes of not getting our living room stirred into the backyard pool. As the strength of gravity between the Milky Way and Andromeda is strong enough to overcome this expansive force. It’s like there’s an invisible gravity rope connecting the two galaxies together. Dragging us to our doom. Curse you, gravity doom rope! Andromeda is speeding towards us at 110 kilometers per second. Without the expansion of the Universe, I’m sure it would be faster and even more horrifying! It’s the same reason why the Solar System doesn't get torn apart. The expansion rate of the Universe is infinitesimally small at a local level. It’s only when you reach hundreds of millions of light-years does the expansion take over from gravity. You can imagine some sweet spot, where a galaxy is falling towards us exactly as fast as it’s being carried away by the expansion of the Universe. It would remain at roughly the same distance and then we can just be friends, and they don’t have to get all up in our biz. If Andromeda starts complaining about being friend-zoned, we’ll give them what-for and begin to re-evaluate our friendship with them, because seriously, no one has time for that. The discovery of dark energy in 1998 has made this even more complicated. Not only is the Universe expanding, but the speed of expansion is accelerating. Eventually distant galaxies will be moving faster away from us than the speed of light. Only the local galaxies, tied together by gravity will remain visible in the sky, eventually all merging together. Everything else will fall over the cosmic horizon and be lost to us forever. All things in the Universe are speeding away from us, it’s just that gravity is a much stronger force at local levels. This is why the Solar System holds together, and why Andromeda is moving towards us and in about 4 billion years or so, the Andromeda galaxy is going to slam into the Milky Way.

Mind Blowing! ...Earth Compared To The Rest Of The Universe  - Amazing Graphic Presentation

Check out more awesome BuzzFeedBlue videos! http://bit.ly/YTbuzzfeedblue1 “There are more stars in our Universe than there are grains of sand on all the beaches on Earth.” There are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe – maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe – a 1 followed by 22 zeros. At the high end, it’s 200 sextillion. These are mind bogglingly huge numbers. How do they compare to the number of grains of sand on the collective beaches of an entire planet? This type of sand measures about a half millimeter across. You could put 20 grains of sand packed in side-by-side to make a centimeter. 8000 grains in one cubic centimeter. If you took 10 sextillion grains of sand, put them into a ball, it would have a radius of 10.6 kilometers. And for the high end of our estimate, 200 sextillion, it would be 72 kilometers across. If we had a sphere bigger than the Earth, it would be an easy answer, but no such luck. This might be close. So, is there that much sand on all the beaches, everywhere, on this planet? You’d need to estimate the average volume of a sandy beach and the average amount of the world’s coastlines which are beaches. The estimates and calculations made by Dr. Jason Marshall, aka, the Math Dude are that, there about 700 trillion cubic meters of beach of Earth, and that works out to around 5 sextillion grains of sand.

The Biggest Stars In The Universe

Science & Reason on Facebook: http://tinyurl.com/ScienceReason Star Size Comparison: The biggest/largest known stars in the Universe. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- VY Canis Majoris (VY CMa) is a red hypergiant star located in the constellation Canis Major. With a size of 2600 solar radii, it is the largest known star and also one of the most luminous known. It is located about 1.5 kiloparsecs (4.6×1016 km) or about 4,900 light years away from Earth. Unlike most stars, which occur in either binary or multiple star systems, VY CMa is a single star. It is categorized as a semiregular variable and has an estimated period of 6,275,081 days, or just under 17,200 years. Antares is a red supergiant star in the Milky Way galaxy and the sixteenth brightest star in the nighttime sky (sometimes listed as fifteenth brightest, if the two brighter components of the Capella quadruple star system are counted as one star). Along with Aldebaran, Spica, and Regulus it is one of the four brightest stars near the ecliptic. Antares is a variable star, whose apparent magnitude varies from +0.9 to +1.8. The Pistol Star is a blue hypergiant and is one of the most luminous known stars in the Milky Way Galaxy. It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region. The star owes its name to the shape of the Pistol Nebula, which it illuminates. It is located approximately 25,000 light years from Earth in the direction of Sagittarius. It would be visible to the naked eye as a fourth magnitude star, if it were not for the interstellar dust that completely hides it from view in visible light. Rigel (β Ori / β Orionis / Beta Orionis) is the brightest star in the constellation Orion and the sixth brightest star in the sky, with visual magnitude 0.18. Although it has the Bayer designation "beta", it is almost always brighter than Alpha Orionis (Betelgeuse). Aldebaran (α Tau, α Tauri, Alpha Tauri) is an orange giant star located about 65 light years away in the zodiac constellation of Taurus. With an average apparent magnitude of 0.87 it is the brightest star in the constellation and is one of the brightest stars in the nighttime sky. The name Aldebaran is Arabic (الدبران al-dabarān) and translates literally as "the follower", presumably because this bright star appears to follow the Pleiades, or Seven Sisters star cluster in the night sky. This star is also called the Bull's Eye because of its striking orange color and its location in the bull's head shaped asterism. NASA's Pioneer 10 spacecraft, which flew by Jupiter in 1973, is currently traveling in the direction and will reach it in about two million years. Arcturus (α Boo / α Boötis / Alpha Boötis) is the brightest star in the constellation Boötes. With a visual magnitude of −0.05, it is also the third brightest star in the night sky, after Sirius and Canopus. It is, however, fainter than the combined light of the two main components of Alpha Centauri, which are too close together for the eye to resolve as separate sources of light, making Arcturus appear to be the fourth brightest. It is the second brightest star visible from northern latitudes and the brightest star in the northern celestial hemisphere. The star is in the Local Interstellar Cloud. Pollux (β Gem / β Geminorum / Beta Geminorum) is an orange giant star approximately 34 light-years from the Earth in the constellation of Gemini (the Twins). Pollux is the brightest star in the constellation, brighter than Castor (Alpha Geminorum). As of 2006, Pollux was confirmed to have an extrasolar planet orbiting it. Sirius is the brightest star in the night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The name Sirius is derived from the Ancient Greek Σείριος. The star has the Bayer designation α Canis Majoris (α CMa, or Alpha Canis Majoris). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The Sun is the star at the center of the Solar System. The Sun has a diameter of about 1,392,000 kilometres (865,000 mi) (about 109 Earths), and by itself accounts for about 99.86% of the Solar System's mass; the remainder consists of the planets (including Earth), asteroids, meteoroids, comets, and dust in orbit. About three-fourths of the Sun's mass consists of hydrogen, while most of the rest is helium. http://en.wikipedia.org/wiki/Largest_stars --- CREDITS Animations: morn1415, NASA, ESO, Hubblecast Editing: http://www.youtube.com/Best0fScience .

3 Things 'Faster Than Light'
 
03:50
These 3 things go "faster" than the speed of light. How's that even possible? Subscribe: http://www.youtube.com/channel/UCj1gf... ↓Want more info?↓ More about the experiment: Marissa Giustina’s research: http://arxiv.org/abs/1511.03190 Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since "accelerated" to faster than the speed of light. You might go further and say that there are more distant galaxies that we can't see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn't from doppler and this "acceleration" of the expanding universe isn't actually causing a true increase in velocity. Sometimes astronomers do say there is a faster than light "recession speed" by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that's misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

Crash of the Titans: Milky Way and Andromeda Galaxy
 
04:29
http://www.facebook.com/ScienceReason ... Hubblecast Episode 55: Crash of the Titans. Astronomers have used the NASA/ESA Hubble Space Telescope to forecast a future cosmic pile up: the titanic collision of the Milky Way and the Andromeda galaxy in about four billion years time. --- Please subscribe to Science & Reason: • http://www.youtube.com/ScienceTV • http://www.youtube.com/Best0fScience • http://www.youtube.com/FFreeThinker --- In this episode of the Hubblecast, scientists Jay Anderson and Roeland van der Marel show how they have used Hubble observations to predict the future of the Andromeda Galaxy and the Milky Way. The Andromeda Galaxy, some 2.2 million light-years away, is the closest spiral galaxy to our home, the Milky Way. For around a century, astronomers have known it is moving towards us, but whether or not the two galaxies would actually collide, or simply fly past each other, remained unclear. Now, a team of astronomers has used the Hubble Space Telescope to shed light on this question, by looking at the motion stars in the Andromeda Galaxy. We wanted to figure out how Andromeda was moving through space. So in order to do that we measured the location of the Andromeda stars relative to the background galaxies. In 2002 they were in one place, and in 2010 they were in a slightly different place. And that allowed us to measure the motion over a period of eight years. The motion is actually incredibly subtle, and not obvious to the human eye, even when looking at Hubble's sharp images. However, sophisticated image analysis revealed tiny movements that the scientists were able to project into the future. Based on these findings, it is finally possible to show what will happen to the Milky Way over the next eight billion years, as the galaxies drift closer then collide and gradually merge into a single, larger, elliptical galaxy with reddish stars. And yet the Solar System should in fact survive this huge crash. The reason we think that our Solar System will not be much affected by this collision between the Milky Way and Andromeda is that galaxies are mostly empty space. Even though our galaxy, as well as the Andromeda Galaxy, has a hundred billion stars in it, they are very far apart. So if two galaxies actually collide with each other, the stars basically pass right between each other and the chance of two stars directly hitting each other is really, really small. So the likelihood that our Solar System will be directly impacted by another star, for example, in Andromeda as we collide with it is really, really small. If life is still present on Earth when this happens, the changes in the sky will be quite spectacular. Now they will be very very slow because the timescales on the scales of galaxies in the Universe are very very long. So you have to think, millions of years but even then over these timescales over millions of years, we will see big changes. If we wait a few billion years, Andromeda will be huge on the sky. It will be as big as our Milky Way because we'll be very close to it. And then later, when the galaxies merge, the merged remnant of the Milky Way Galaxy and Andromeda will look more like an elliptical galaxy and we'll be sitting right in it. So the view of the Milky Way on the night sky will be completely gone and this band of light will be replaced by a more spheroidal distribution of light. And so, the Sun, born in the Milky Way almost 5 billion years ago will end its life in a new orbit, as part of a new galaxy. --- Keywords: Andromeda Milky Way Galaxy crash of the titans collide collision spiral elliptical galaxies NASA ESA Hubble Space Telescope stars universe light images astronomers astronomy science videos Hubblecast 55 .

Misconceptions About the Universe
 
05:46
Can we see things travelling faster than light? Check out Audible: http://bit.ly/AudibleVe Music by Amarante "One Last Thing" http://bit.ly/VeAmarante Awesome animations by http://youtube.com/minutephysics Thanks to Prof. Geraint Lewis for input on earlier drafts of this video. The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere - it's limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.

What's Inside A Black Hole?
 
09:16
What's Inside A Black Hole? Subscribe: https://goo.gl/GmtyPv Black holes are mysterious and bizarre objects in the universe that really have no explanation. In fact, we hardly know anything about what lies inside of a black hole. We know and understand what we see on the outside of a black hole, but we have no way of going inside one to take a look at what is really happening. Even if we sent a probe inside a black hole, it would not survive the journey, and there would be no way that the probe could transmit a signal outside once it had been sucked inside. This is because a black hole is the product of mass being squeezed together so densely, and so tightly, that it creates a gravitational pull that is so strong, that not even light can escape its grasp. Supermassive black holes with masses millions to billions of times that of the sun are thought to lurk at the hearts of all galaxies in the universe. You may notice that when you see a photo of a spiral galaxy, such as the Milky Way, in the center of the galaxy is a giant mass of light, which many people would think looks like a massive sun. But this is not light coming from the black hole itself. Remember, that light cannot escape the heavy gravitational pull. Instead, the light we see comes from the magnetic fields near a spinning black hole that propel electrons outward in a jet along the rotation axis. The electrons produce bright radio waves. Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located. Because quasars are so bright, they drown out the light from all the other stars in the same galaxy. You’re probably asking, ‘well, what’s a quasar?’ A Quasar is the short name for ‘quasi-stellar object’ and is a very highly energetic object surrounding an actively feeding Supermassive Black Hole. In more basic terms, the Supermassive Black Hole in the middle of a galaxy feeds intermittently. As it feeds, gas swirls around it at incredible speeds and forms an insanely bright hot orbiting disk. And if the black hole is swallowing a large amount of material, this feeding is accompanied by gigantic jets of gas. These are called Quasar. They are essentially fueled by the Black Holes they orbit.

Whether it's clouds that rain rocks or glass, wind that's 29 times faster than sound, having 2 shadows or even being able to fly in some places, this is a collection of some of the most ridiculous places that we know of so far in our strange universe. This video was done in a collaboration with Second Thought, and you can check out his video here! If you're curious about flying on Titan and the research into that, I've attached a paper written by the Department of Physics and Astronomy at the University of Leicester dated October 22nd 2013 which goes into a lot more detail than I could afford.

The Largest Black Holes in the Universe
 
24:59
Our Milky Way may harbor millions of black holes... the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power. Just how large, and violent, and strange can they get? A new era in astronomy has revealed a universe long hidden to us. High-tech instruments sent into space have been tuned to sense high-energy forms of light -- x-rays and gamma rays -- that are invisible to our eyes and do not penetrate our atmosphere. On the ground, precision telescopes are equipped with technologies that allow them to cancel out the blurring effects of the atmosphere. They are peering into the far reaches of the universe, and into distant caldrons of light and energy. In some distant galaxies, astronomers are now finding evidence that space and time are being shattered by eruptions so vast they boggle the mind. We are just beginning to understand the impact these outbursts have had on the universe: On the shapes of galaxies, the spread of elements that make up stars and planets, and ultimately the very existence of Earth. The discovery of what causes these eruptions has led to a new understanding of cosmic history. Back in 1995, the Hubble space telescope was enlisted to begin filling in the details of that history. Astronomers selected tiny regions in the sky, between the stars. For days at a time, they focused Hubble's gaze on remote regions of the universe. These hubble Deep Field images offered incredibly clear views of the cosmos in its infancy. What drew astronomers' attention were the tiniest galaxies, covering only a few pixels on Hubble's detector. Most of them do not have the grand spiral or elliptical shapes of large galaxies we see close to us today. Instead, they are irregular, scrappy collections of stars. The Hubble Deep Field confirmed a long-standing idea that the universe must have evolved in a series of building blocks, with small galaxies gradually merging and assembling into larger ones.

Universe: Beyond the Millennium - Alien Life
 
50:15
"Universe: Beyond the Millennium" is a television series observing astronomical phenomena, research, and theories on the universe and its origins. Narrated by John Hurt. The documentary premiered in 1999 and presents an overview of the universe as humans understood it at that time, and how we think it will evolve in the next millennium. Using 3D computer generated graphics, the series features animated sequences that offer insight into the Big Bang theory and the anatomy of the sun. "Alien Life", when NASA scientists found a lump of rock from Mars with microscopic fossils in it, the search for extraterrestrial life beyond our own became a credible objective. Researchers and scientists from SETI (Search for Extra-Terrestrial Intelligence) have spent decades trying to determine how an alien life force would contact us and if one does, how we would reply. At the start of a new millennium we're about to embark on the greatest adventure of all time. Five hundred million miles from Earth, a spacecraft will land on Jupiter's icy moon, Europa. It's mission, to search for alien life. As we reach out across the galaxy, our spacecraft will explore the most extreme environments to answer the ultimate question, are we alone?

One of the most counterintuitive facts of our universe is that you can’t go faster than the speed of light. From this single observation arise all of the mind-bending behaviors of special relativity. But why is this so? In this in-depth video, Fermilab’s Dr. Don Lincoln explains the real reason that you can’t go faster than the speed of light. It will blow your mind.

How Large is the Universe?
 
25:04
The universe has long captivated us with its immense scales of distance and time. How far does it stretch? Where does it end, and what lies beyond its star fields and streams of galaxies extending as far as telescopes can see? These questions are beginning to yield to a series of extraordinary new lines of investigation and technologies that are letting us to peer into the most distant realms of the cosmos. But also at the behavior of matter and energy on the smallest of scales. Remarkably, our growing understanding of this kingdom of the ultra-tiny, inside the nuclei of atoms, permits us to glimpse the largest vistas of space and time. In ancient times, most observers saw the stars as a sphere surrounding the earth, often the home of deities. The Greeks were the first to see celestial events as phenomena, subject to human investigation rather than the fickle whims of the Gods. One sky-watcher, for example, suggested that meteors are made of materials found on Earth... and might have even come from the Earth. Those early astronomers built the foundations of modern science. But they would be shocked to see the discoveries made by their counterparts today. The stars and planets that once harbored the gods are now seen as infinitesimal parts of a vast scaffolding of matter and energy extending far out into space. Just how far began to emerge in the 1920s. Working at the huge new 100-inch Hooker Telescope on California's Mt. Wilson, astronomer Edwin Hubble, along with his assistant named Milt Humason, analyzed the light of fuzzy patches of sky... known then as nebulae. They showed that these were actually distant galaxies far beyond our own. Hubble and Humason discovered that most of them are moving away from us. The farther out they looked, the faster they were receding. This fact, now known as Hubble's law, suggests that there must have been a time when the matter in all these galaxies was together in one place. That time, when our universe sprung forth, has come to be called the Big Bang. How large the cosmos has gotten since then depends on how long its been growing and its expansion rate. Recent precision measurements gathered by the Hubble space telescope and other instruments have brought a consensus... That the universe dates back 13.7 billion years. Its radius, then, is the distance a beam of light would have traveled in that time ... 13.7 billion light years. That works out to about 1.3 quadrillion kilometers. In fact, it's even bigger.... Much bigger. How it got so large, so fast, was until recently a deep mystery. That the universe could expand had been predicted back in 1917 by Albert Einstein, except that Einstein himself didn't believe it until he saw Hubble and Humason's evidence. Einstein's general theory of relativity suggested that galaxies could be moving apart because space itself is expanding. So when a photon gets blasted out from a distant star, it moves through a cosmic landscape that is getting larger and larger, increasing the distance it must travel to reach us. In 1995, the orbiting telescope named for Edwin Hubble began to take the measure of the universe... by looking for the most distant galaxies it could see. Taking the expansion of the universe into account, the space telescope found galaxies that are now almost 46 billion light years away from us in each direction... and almost 92 billion light years from each other. And that would be the whole universe... according to a straightforward model of the big bang. But remarkably, that might be a mere speck within the universe as a whole, according to a dramatic new theory that describes the origins of the cosmos.

Why We Cant Find Extraterrestrial Life - The Fermi Paradox
 
09:11
One of the biggest paradoxes is that despite there being billions of other stars with earth like planets out there and according to the Drake equation, there should be 100's or 1000's of advanced civilisations. But so far we have found nothing to prove that intelligent life exists anywhere else other than here on Earth. Patreon : https://www.patreon.com/curiousdroid Paypal.me : https://www.paypal.me/curiousdroid You can now translate this and other curious droid videos, see my video about it here https://www.youtube.com/watch?v=xLPVgIytKyg Earth Isn’t As special As We like to Think We humans do tend to hold ourselves in high regard when it come to the rest of the Cosmos. For thousands of years we believed that we and earth, were at the center of the universe and everything revolved around us including the sun and the stars. We now know that our sun is just one of billions of very similar stars and earth is a planet that is not that special. We often think that aliens would want to come to our home planet for our resources, the water, minerals, possibly the life that exists here and maybe to communicate with us humans. But if an alien race is capable of travelling and communicating across light years of space and would be 1000’s or millions of years ahead of us in their development. They’ve Moved Out Of The Universe One reason why we have not seen an evidence of advanced civilizations is that they have evolved out of this universe to another or into another dimension. According to futurist John Smart’s Transcension Hypothesis, intelligent alien life once existed in our universe, yet it became so advanced that it moved on the sub atomic scale or inner space rather than outer space. Whilst this may sound like something from the pages of a sci-fi novel as lot of thought has been put in to it. https://www.youtube.com/watch?v=HttdxjYK7EQ https://www.youtube.com/watch?v=IN1KJ8LYW3U https://www.youtube.com/watch?v=SeGqCl3YAaQ https://www.youtube.com/watch?v=x-a-aCOscE4 https://www.youtube.com/watch?v=gZxLUNHEmPw https://www.youtube.com/watch?v=-H_HZVY1tT4 https://www.youtube.com/watch?v=lQ2m-GSaX8E https://www.youtube.com/watch?v=K1yfeEqcmaQ Galaxy 2005 The Return by Frank Dorittke is licensed under a Creative Commons Attribution licence (http://creativecommons.org/licenses/by-nc-nd/3.0/) Source: http://freemusicarchive.org/music/Frank_Dorittke/Mare_Tranquillitatis/pcr018_cd02_02_fd_project_galaxy_2005_the_return Artist: http://freemusicarchive.org/music/Frank_Dorittke/

What Lies Beyond The Edge of the Universe?

Universe, space, planets, stars. Is there a limit to our reality? BonusVideo @ Patreon: http://www.patreon.com/strangemysteries Narration provided by JaM Advertising New Mexico www.tasteofjam.com Planets, stars, galaxies, clusters, space. The universe as we know it is made up of many different things, much of which we may never be able to understand or even see. But is there a limit to our reality? How far does the universe go? Does it even have an end? And if so, could anything exist outside of that? As we're about to find out, the answer to this question isn't straightforward at all, but let's give it our best shot in our video which seeks to answer, what lies beyond the edge of the universe. Imagine if you were to somehow reach the very edge of the known universe. That's an epic journey of immense proportions for a start, but if you could somehow survive the trip, what would you see? Darkness? Light? Or something else? One recently developed idea seeks to take us back to the beginning of the universe itself to find an answer. The theory, proposed by Dr Julian Barbour, Dr Tim Koslowski and Dr Flavio Mercati claims that when the big bang created our universe, we were not an only child. Our universe has a twin, and a rather bizarre one at that. When scientists are attempting to find black holes they don't do so by looking for them directly, as since they emit no light this would be impossible. Instead, they detect them by observing their effects on surrounding objects such as planets and stars. Black holes are so incredibly powerful that they cause hugely noticeable effects on the light we receive from stars light years away, and the reason this is relevant is because we can also use this method to examine the edges of our own universe. Let's scale back from these grandiose theories and explore a theory that's based on things we know for certain, the things we've seen and measured - i.e. the size of the observable universe. We could start this entry by throwing a huge number at you, but that wouldn't mean much without context. So let's build up nice and gently. Humans, you are on average 1.6 to 1.7 metres tall. Your typical tree is around ten times that, and the tallest tree in the world is the redwood at over 100 metres high. The tallest man-made object on Earth is the Burj Khalifa at 828 metres, and currently under construction is Saudi Arabia's Jeddah Tower, with this building set to be the world's first to go beyond a kilometre in height. But that's nothing compared to Mount Everest, which reaches 8.8 kilometres at its peak.

Are There Antimatter Galaxies? How We'd Find Them Across the Universe
 
05:30
One of the big mysteries in astronomy is what happened to all the antimatter? Is it possible that it’s actually still out there, in huge antimatter galaxies? Support us at: http://www.patreon.com/universetoday More stories at: http://www.universetoday.com/ Follow us on Twitter: @universetoday Follow us on Tumblr: http://universetoday.tumblr.com/ Like us on Facebook: https://www.facebook.com/universetoday Google+ - https://plus.google.com/+universetoday/ Instagram - http://instagram.com/universetoday Team: Fraser Cain - @fcain Jason Harmer - @jasoncharmer Chad Weber - [email protected] Created by: Fraser Cain and Jason Harmer Edited by: Chad Weber Music: Left Spine Down - “X-Ray” https://www.youtube.com/watch?v=4tcoZNrSveE One of the biggest mysteries in astronomy is the question, where did all the antimatter go? Shortly after the Big Bang, there were almost equal amounts of matter and antimatter. I say almost, because there was a tiny bit more matter, really. And after the matter and antimatter crashed into each other and annihilated, we were left with all the matter we see in the Universe. You, and everything you know is just a mathematical remainder, left over from the great division of the Universe’s first day. We did a whole episode on this mystery, so I won’t get into it too deeply. But is it possible that the antimatter didn’t actually go anywhere? That it’s all still there in the Universe, floating in galaxies of antimatter, made up of antimatter stars, surrounded by antimatter planets, filled with antimatter aliens? Aliens who are friendly and wonderful in every way, except if we hugged, we’d annihilate and detonate with the energy of gigatons of TNT. It’s sort of tragic, really. If those antimatter galaxies are out there, could we detect them and communicate with those aliens? First, a quick recap on antimatter. Antimatter is just like matter in almost every way. Atoms have same atomic mass and the exact same properties, it’s just that all the charges are reversed. Antielectrons have a positive charge, antihydrogen is made up of an antiproton and a positron (instead of a proton and an electron). It turns out this reversal of charge causes regular matter and antimatter to annihilate when they make contact, converting all their mass into pure energy when they come together. We can make antimatter in the laboratory with particle accelerators, and there are natural sources of the stuff. For example, when a neutron star or black hole consumes a star, it can spew out particles of antimatter. In fact, astronomers have detected vast clouds of antimatter in our own Milky Way, generated largely by black holes and neutron stars grinding up their binary companions. But our galaxy is mostly made up of regular matter. This antimatter is detectable because it’s constantly crashing into the gas, dust, planets and stars that make up the Milky Way. This stuff can’t get very far without hitting anything and detonating. Now, back to the original question, could you have an entire galaxy made up of antimatter? In theory, yes, it would behave just like a regular galaxy. As long as there wasn’t any matter to interact with. And that’s the problem. If these galaxies were out there, we’d see them interacting with the regular matter surrounding them. They would be blasting out radiation from all the annihilations from all the regular matter gas, dust, stars and planets wandering into an antimatter minefield. Astronomers don’t see this as far as they look, just the regular, quiet and calm matter out to the edge of the observable Universe. That doesn’t make it completely impossible, though, there could be galaxies of antimatter as long as they’re completely cut off from regular matter. But even those would be detectable by the supernova explosions within them. A normally matter supernova generates fast moving neutrinos, while an antimatter supernova would generate a different collection of particles. This would be a dead giveaway. There’s one open question about antimatter that might make this a deeper mystery. Scientists think that antimatter, like regular matter, has regular gravity. Matter and antimatter galaxies would be attracted to each other, encouraging annihilation. But scientists don’t actually know this definitively yet. It’s possible that antimatter has antigravity. An atom of antihydrogen might actually fall upwards, accelerating away from the center of the Earth. Physicists at CERN have been generating antimatter particles, and trying to detect if they’re falling downward or up. If that was the case, then antimatter galaxies might be able to repel particles of regular matter, preventing the annihilation, and the detection.

Dear world, Let´s talk about time. When I uploaded my first YouTube video 7 years ago, I would have never thought that it would get that much attention. Had lots of discussions, met new people, continued to make videos about things that intrigued me. Or tried out effects. I enjoyed it a lot, and I still read every comment that pops up. And they keep coming in. It is a hobby that I am very glad about having started. And I am humbled by the attention. Well, as time went by I found less time to work on videos, struggled with other things in life, and wondered if I would ever find the time again. But I always knew one thing: I owe you something. All the time people were are asking about a sequel to starsize comparison. And yes, I promised once. I keep my promises. So, whenever I found time over the last year I spent it on that. Here it is. I hope you like it. I tried to do it in a bit different way. Curious for the feedback.

Still looking for contact to musicians. I do not know what the future brings, but I hope we will hear from each other. Enjoy.

Many of you said it was the most depressing episode I’ve ever done . The distance to Pluto is, on average, about 40 astronomical units. That’s 40 times the distance from the Sun to the Earth. And New Horizons, the fastest spacecraft traveling in the Solar System took about 10 years to make the journey. The distance to Alpha Centauri is about 277,000 astronomical units away (or 4.4 light-years). That’s about 7,000 times further than Pluto. New Horizons could make the journey, if you were willing to wait about 70,000 years. That’s about twice as long as you’d be willing to wait for Half Life 3.

In early April, 2016, just 8 months after I said it was probably never going to happen, the billionaire Yuri Milner and famed physicist Stephen Hawking announced a strategy to send a spacecraft to another star within our lifetime. In your face Fraser, they said... in your face. The project will be called Breakthrough Starshot, and it’s led by Pete Worden, the former director of NASA’s AMES Research Center - the people working on a warp drive. The team announced that they’re spending $100 million to investigate the technology it’ll take to send a spacecraft to Alpha Centauri, making the trip in just 20 years. And by doing so, they might just revolutionize the way spacecraft travel around our own Solar System. So, what’s the plan? According to their announcement, the team is planning to create teeny tiny lightsail spacecraft, and accelerate them to 20% the speed of light using lasers. Yes, everything’s made better with lasers . We’ve talked about solar sails in the past, but the gist is that photons of light can impart momentum when they bounce off something. It’s not very much, but if you add a tremendous amount of photons, the impact can be significant. And because those photons are going the speed of light, the maximum speed for the spacecraft, in theory, is just shy of the speed of light (thanks relativity). You can get those photons from the Sun, but you can also get them from a directed laser beam, designed to fill the sails with photons, without actually melting the spacecraft. In the past, engineers have talked about solar sails that might be thousands of kilometers across, made of gossamer sheets of reflective fabric. Got that massive, complicated sail in your mind? Now think smaller. The Starshot spacecraft will measure just a few meters across, with a thickness of just a few atoms. The sail would then pull a microscopic payload of instruments. A tiny chip, capable of gathering data and transmitting information - these are called Starchips. Not even enough room for water bear crew quarters. With such a low mass, a powerful laser should be able to accelerate them to 20% the speed of light, almost instantly, making a trip to Alpha Centauri only take about 20 years. Since each Starshot might only cost a few dollars to make, the company could manufacture thousands and thousands, place them into orbit, and then start bugzapping them off to different stars. There are, of course, some massive engineering hurdles to overcome. The first is the density of the interstellar medium. Although it’s almost completely empty in between the stars, there are the occasional dust particles. Normally harmless, the Starshots would be smashing into them at 20% the speed of light, which would be catastrophic. The second problem is that this is a one-way trip. Once it’s going 20% the speed of light, there’s no way to slow the spacecraft down again (unless the Alpha Centaurans have a braking system in place). Just imagine the motion blur and targeting problems when you’re trying to take photos at relativistic speeds.
