A Journey to the End of the Universe


What will happen to us in the next few hundred
years? Or a thousand? How will the Universe end? How the heck should I know? Hey, nobody knows for sure, but we can gather
all the existing theories together and find it out. Good thing we’ve got this time projector
here to check it out with our own eyes! C’mere and have a look! Let’s start with our own near future. In 10 years, you’ll be 10 years older. High percentage of probability there. In 100 years, technology will leap forwards,
and we’ll all become part of a web larger than the Internet. We’ll also finally start colonizing nearby
planets, most likely Mars. Just a century from now humans will be the
first living species outside Earth that we know of. Cool, huh? But it gets better! Hopping another 900 years forward, to the
next millennium. In 1,000 years, humanity will accept technology
not only in their lives but inside their bodies too. Ever heard about cyborgs? If that’s too sci-fi for you, well, get
ready for a bit of a shocker: that’s exactly what every other human being will become in
the future. And here goes… 10,000 years from today. Antares, the red supergiant star that is fifteenth
brightest in our night sky, will explode in a supernova. This glorious event will be visible with a
naked eye even in broad daylight… if there still is a human eye to behold it. 100,000 years in the future — and many of
the constellations we know will become unrecognizable because of the natural movement of stars. At nearly the same time, VY Canis Majoris,
another super-bright star, will explode in a hypernova — a much more powerful version
of a supernova, destroying dozens or even hundreds of nearby planets and their satellites. And Earth will celebrate the distant anniversary
by a supervolcanic eruption, with hot magma and volcanic ash covering thousands upon thousands
of square miles of land. In 500,000 years, our planet will be struck
with a huge boulder from the sky: an asteroid of about a half mile in diameter. If humans don’t find a way to avoid the
impact, it will cause mass destructions on Earth. In 1 million years, two out of four moons
of Uranus will collide with each other, causing chaos on the planet. At the same time, Betelgeuse, one of the brightest
stars in our galaxy, will explode, clearly visible from Earth. Just 400,000 years later, Phobos, one of Mars’s
two satellites, will break apart because of increasing gravity, and the red planet will
have its own set of rings, just like Saturn. And somewhere far away, at the edge of the
Solar system, a rogue star called Gliese 710 will enter the Oort cloud, which is a field
of icy comets marking the borders of our system. Because of this star, many of those comets
might turn in the Earth’s direction, eventually bombarding it from space. 110 million years from now is when the Sun
will become 1% brighter. It will change the climate on every planet
in the Solar system, ever so slightly making it hotter and hotter still. At 2 billion years’ mark, the Sun’s luminosity
will make oceans evaporate on Earth. The life on our planet will cease to exist
in all but the simplest forms… which will soon go extinct as well. 4 billion years from now the Milky Way galaxy
will collide with the Andromeda galaxy. Supermassive black holes in the centers of
both of them will get close to each other and begin merging into one — a hypermassive
black hole that has a mass of billions of Suns. And that will mark the birth of a brand new
galaxy: Milkdromeda. Or maybe, Andway. And they’ll have big sales conventions and
try to get you to join. In 7.9 billion years, the Sun will become
super-inflated and turn into a red giant, swallowing the closest planets — including
the scalding hot piece of rock that was once Earth. But the star only does so to collapse into
a white dwarf in 8 billion years. All planets of the Solar system that survive
this ordeal will quickly lose heat because the Sun will become twice as small as it is
today. In 100 billion years, the Universe will stretch
so far and so fast that galaxies will become invisible from each other’s perspective. The Universe is constantly expanding, and
the rate of this stretching is growing too. Some say it’s faster than the speed of light,
which makes it impossible to see the actual edge of the Universe by any means. In 1 trillion years, new stars will stop appearing
in space. The ever-expanding universe will stretch so
much that the distance between stars and galaxies is just too big. There will be no gas clouds, and thus no material
for new stars to take shape. In 100 trillion years, the Degenerate Era
will begin. With no fuel to feed the new stars, they will
simply stop forming at all, even if some tried at first. At the same time, the existing stars will
slowly fade, turning from bright object into dwarves — red, blue, white, and brown. In 120 trillion years, only white and brown
dwarf stars will remain where normal stars have once been. All of them will have lost all their fuel,
and space will be scattered with the fading remnants of stars. The Universe will become a dark place to live
in. Occasional brown dwarfs will collide with
each other, merging into red dwarves for short periods of time. But in the end, with no fuel to burn, those
too will be extinguished, and there will only be darkness. In 1 quadrillion years, all planets will be
thrown out of their orbits and sent drifting in the cold, dark outer space. Nothing will be able to live on any of those
planets anymore, and nothing could reignite any of the stars in space. 1 quintillion years, and things that once
were stars will also become ejected from their galaxies, wandering the empty Universe for
the rest of their time. Which is, by space standards, not very long. In 1045 years, even particles that make up
everything material in the Universe will start to decay. And when they finish that process, the Black
Hole Era will begin: black holes will be the only objects remaining in the Universe. The rest will be wiped out. But even black holes are not eternal. They will all decay too, and that will happen
in about 10107 years from now. What will remain after they disappear is almost
pure vacuum, filled with tiny subatomic particles. There will be a vast, incomprehensible ocean
of emptiness, until even those little things disappear too, making the Universe an absolute
void. Now, for quintillions of quintillions of years,
there will be nothing; this period is called the Dark Era, and time won’t matter at this
point. But then, if we leap forward an innumerable
amount of years… what’s this? The space seems to be moving. It’s… rippling. The ripples are getting bigger and wider,
taking in more and more of the empty Universe, but how could this even happen in the utter
vacuum? Well, that’s because of the false vacuum
that exists alongside the real one. No one knows exactly what it is, but if you
watch long enough, you’ll see… Ah, there you have it. The false vacuum has just inflated and heated
up to extreme temperatures, exploding in the empty space and filling it with new energy. Giving life to the new universe — and possibly
not even a single one. You know this event as the Big Bang. That’s how our Universe was born, and how
it will probably be reborn after billions upon billions of years. Bottom Line: Right now seems to me like a
pretty good time to be alive. Make sure to get outside and play some today. Work can wait. So can the Universe. So there, Bright Sider! Hey, if you learned something new today, then

  1. I think this is a fake video
    I mean come on i don't see how anyone can predict what is going to happen quintillions of years later.

    Edit : We can't even predict the weather for the next week correctly πŸ˜…πŸ˜…πŸ˜…

  2. so basically a reset of the whole life and such to then have the vacuum been vacuumed long enough to generate heat making particles that colade either do fast or gravity that it will explode into some material creating stats that when they go boom more material gets made????

  3. Makes me think of all the hard work of a civilization to survive for thousands and thousands of years will all go to waste at some point.

  4. 😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😨😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱

  5. Now you scared me πŸ‘»πŸ˜’.But i believe there is no such type of "alien" πŸ‘½ in our universe, it us who be first civilization to be colonised on other planets…then who be called aliens now? πŸ€”

  6. 3:32 like the old time people
    Yeah you know it eart back to her own time and mars get her own time

    Edit:30billion year before human exists earth was like mars and mars like earth

  7. How tf do you know whats going to happen billions of years from now. How do ppl come up with this. πŸ€·πŸΎβ€β™‚οΈvery entertaining tho

  8. So basically everything that is born must die at some point in time. Nothing lives for ever including time itself……. wow!!!

  9. 021.104 .The Day when We will fold the heaven like the folding of a [written] sheet for the records. As We began the first creation, We will repeat it. [That is] a promise binding upon Us. Indeed, We will do it.

  10. It’s happy that the Universe is repeating and repeating it’s cycle hopefully there will be another being simpler to humans!

  11. Dud you are the best but also I will get night mares but also good new the planet's will reborn I wonder is it like a recycle maybe everything is a recycle pls tell me I ask my science teachers they say I'm too youngπŸ˜‘πŸ˜‘πŸ˜

  12. Hey! If you know the universe better than us, do you know the Beginning to end? What will destroy every living thing. Nothing remaking it. What will happen!? We. All known the begening end but how bout the end of the END?
    No lies truth. We may never know what will happen in our lives.

  13. Guys all of this is fake earth o my has been here for 8 thousand years god made earth and evolution is fake Jesus will make his return by then

  14. This was told by Hindu scriptures centuries ago that Shiva the God will destroy universe and will create new one so true

  15. Really…
    Really…
    This video became my favourite video of all the time, as a cosmology lover πŸ˜πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€πŸ–€

  16. wait wait wait wait universe will be reborn again that was such πŸ₯³πŸ₯³πŸ₯³πŸ˜‡πŸ˜‡πŸ§πŸ‘πŸ‘πŸ‘πŸ‘πŸ‘πŸ»πŸ‘πŸ»πŸ‘πŸ»πŸ‘πŸ»a happy ending wow

  17. When everything has ended, and when the Universe will be in the "Dark Ages," only one thing will still be there: The Voyager probes (if not destroyed earlier).

  18. Beautiful theory Brightside , with betelgeuse theory have you calculated the ligthyears? I'm not sure but the 4 million years you spoke of might be some time sooner in earth years if calculated correctly.
