A million years is a very long time to us, but when you think about how old the universe
is, 13.8 billion years old, its really not that long. That being said, a lot can happen
in a million years. Our moon used to be much closer to us a million years ago, and would
have looked much larger in the sky. Species have come and went, and humans have only been
around for around 1 million years. But what about 1 million years in the future? That’s
the question we’re asking, right now on life’s biggest questions.
Hello and welcome back to life’s biggest questions, the channel that questions the
impossible. I’m your host, charlotte dobre, and hit that thumbs up button if you love
videos about space. By the way, if you love our SCP videos, how can you not, check out
our latest one by jack finch What if SCP 682 was real, that’s currently clickable on
your screen. It is extremely difficult to predict the future,
but according to scientific understanding that we currently have, this is what will
happen in a million years. We have already covered what will happen to the earth in 1
million years time, in our video, what will the earth look like in 1 million years. If
you haven’t seen that video, check it out, its clickable on the screen right now. But
the earth is not the center of the universe, so lets explore this topic a little more.
It is believed that in 1 million years, the earth will likely have undergone a super volcanic
eruption. Big enough to erupt 32 thousand kilometers of magma. This eruption will be
comparable to the Toba Super Eruption that took place 75 thousand years ago. The toba
super eruption occurred in Lake Toba, in Sumatra Indonesia. It cause d a global volcanic winter
that was 6 to 10 years long, and a 1000 year cooling episode. Its also likely that the
Yellowstone super volcano will also erupt some time in the next 1 million years.
In 1 million years, Uranus’ moons Desdemona and Cressida, will have collided. In fact,
over the course of 1 million years, the sun and stars will have moved enough that the
current constellations will be scrambled and will look extremely different.
As time goes on, its going to become extremely likely that earth will be bombarded by some
sort of asteroid or comet. Maybe even several asteroids or comets. This is because a million
years from now, another star is going to enter our solar system. The star is called Gilese
710, it’s an orange dwarf star, classified as a rogue star, which roams across the galaxy,
free of gravitational chains. Gilese 710 is going to get as close as 0.14 light years
to the sun, before it moves away. But because this star is going to get so close, its going
to pass through the oort cloud. The oort cloud is a ring of icy and rocky objects that orbit
our solar system. The oort cloud was named after the the astronomer who first theorized
its existence, jan oort. Its hypothesized that the oort cloud is where most long period
coments have come from. It could be that the oort cloud is a halo of particles that’s
actually made up of the remains of the disc of material that formed the sun and the planets
in our solar system. Because the oort cloud is so far away, its possible to disrupted
by the nearby passage of a star, sending objects into the inner solar system. While the star
Gilese 710 passes through it, thats going to increase the likelihood of cometary impact
in the inner solar system, and quite possibly, the earth. A cometary impact will most definitely
cause mass extinction on earth. It might not end all life on earth, but it will be bad,
very bad, for all the life forms that are still around on our planet in one million
years. Of course, while gilese 710 is close to us,
the skies are going to be lit up by yet another star other than our sun. This has actually
happened before. Our sun has a close encounter with 490 to 600 other stars every 1 million
years. So what about humans during all of this? A
million years from now, if humans are still around, will likely have merged with technology
to form bionic beings. We probably wont look anything like what we currently look like.
In fact, according to experts, humans will be unrecogniseable 1 million years from now.
A million years from now, humans will have gained a complete understanding of our universe
by uniting all theoretical equasions to create a unified theory.
Our sun wont really change all that much, but it will start to get hotter. Looking even
further, in 1-2 billion years, the sun will boil our oceans and end all life on earth.
the Andromeda galaxy, as well as the triangulum galaxy, will have merged with our galaxy in
4 billion years time. This will effectively change the structure of the milky way galaxy
as we know it, making one giant galaxy. Lets call it, milkdromeda. Our sun is expected
to go supernova in 5 to 7 billion years, so say goodbye to both venus and mercury, the
earth will be the closest planet to the sun, but it will be pushed outwards. Well there
you have it. Does anyone else get anxiety when they’re talking about space? Lets change
the subject and respond to some of your comments. Haemish – what if I had friends. Awww we’re
your friends haemish. Vizard Girl – what if people didn’t exist.
This is actually a really good question. I would think that the world would be in much
better shape and there would be way more animals than there currently are.
Aza29 –omg you just hit 1 million. We hit it a million a couple weeks ago actually!
But thanks again to all our subscribers for helping us reach this milestone.
