What Would Happen If Earth Fell Into A BLACK HOLE?


What Would Happen If Earth Fell Into A BLACK
HOLE? Blackholes are still somewhat of a mystery
to us, however that may not always be the case. What we do know, is that they’re pretty
scary and our galaxy alone is thought to contain at least 100 million of them. Yes. 100 million. Hello and welcome back to Life’s Biggest
Questions, I am Rebecca Felgate and today I am asking What Would Happen If Earth Fell
Into a Black Hole? Black holes are wandering around our cosmic
hood. Their gravity is so dense that they are not
stuck in orbit of another object. They are also don’t omit any light or radiation
so you can’t see them, making it hard to know exactly where they are. We can, however, see the holes effect on nearby
matter. Unless there is a lot of nearby matter, black
holes can sneak around undetected. There are two types of black holes; supermassive
black holes which are at the heart of every galaxy, and stellar mass black holes, which
are the ones that can really creep up on you. The nearest stellar mass black hole we know
of is thought to be just under 3 thousand light years away and is about 9 times the
mass of our sun. So what is a black hole exactly and why would
it matter if we got close to one. While there is no doubt we have a lot to learn
about them, black holes are very very dense. They’re so heavy, that they start to bend
space and time, inwards. Obviously, if they’re able to bend space,
black holes are denser than our sun, which means if one came close to earth, the gravitational
pull of our solar system would shift… meaning planets would be torn from orbit and likely
smash into one another. If we were able to avoid any planet smashing,
we would quickly discover that earth has become a dart board for asteroids. Asteroids orbit too, and as much smaller rocks,
they would easily be torn from their current paths and hurled towards Earth. This would not be ideal, as this could cause
widespread death and destruction, and possibly a number of fires. If we, by some chance, managed to survive
that, this next part would assure an end to humanity. As we were drawn closer to the black hole,
our atmosphere would be torn away and sucked in, then parts of the planet would break up
itself. Also, the radiation created from all the other
broken apart material from other planets and cosmic junk would be very, very intense. Oh. We might be dead, but what happens then. What happens when we cross the event horizon
and start travelling into that hole. Well, honestly, we don’t know, but there
are some key theories out there. The first is of spaghettification. Some scientists think that at the bottom of
a black hole is a point of singularity. Our earth would be broken apart, molecule
by molecule, in a funnel effect leading down to this dense point of singularity. We would be stretched out like spaghetti,
so thin that we would exist atom on top of atom. Others theories that black holes are not holes,
but doors to the other side of the universe. I don’t want to mind boggle you, but as
black holes already BEND time and space, many think they’re FOLDS in time and space and
that matter comes out of the other side and expands outwards…like a big bang. We know that our universe is expanding, we
can see it. We know that it started in a very hot, dense
place and exploded outwards. Could we have come out of a black hole? Another theory is that, if earth fell into
a black hole, we wouldn’t even notice. Some scientists believe that instead of being
destroyed, any material that touches a black hole turns into a near perfect hologram. So far as we are aware and can hypothesis,
the only way to escape being sucked in by a black hole is to travel faster than the
speed of its gravitational pull, so faster than the speed of light, which is something
we are not even close to be able to doing. Our solar system has been doing find for 4
and half billion years, which suggests we have never come into contact with a black
hole yet, so we probably shouldn’t worry too much. That being said, there could be a risk of
black hole danger on earth. Scientists have created something called a
Large Hadron Collider, which smashes particles together and is thought to be able to create
a black hole. This collider cost billions of dollars and
is designed to help us understand particle physics and the origins of the universe. … but it could be powerful enough to generate
a miniature black hole. Hmm. On that note, we’re going to end the video. What do you think would happen if the earth
