Imagine this, you’re going about your day, maybe you’re driving, maybe you’re sitting
at your desk at work, maybe you’re walking on the street…when suddenly…you feel the
ground begin to shake.
Everyone begins to panic and scream as you despertately look for something to hide under,
or for an open space, but the ground starts to crack underneath you and people all around
begin to fall into the cracks, that reach tens of kilometers down into the earths crust.
So what happened to cause all these earthquakes?
The earth was somehow, split in half.
Hello and welcome back to life’s biggest questions, the channel that imagines the impossible.
I’m charlotte dobre, and I’m your host for this video.
If you love videos about space, give this video a good old thumbs up and subscribe to
life’s biggest questions if you haven’t already.
So What if the earth split in half?
Spoiler alert, it would mean the end of the world as we know it.
First of all, it is highly, highly unlikely that the earth would ever split in half.
Like I’m not kidding guys, there, The earth is a pretty big object.
It would take an extremely powerful force to break the planet into two pieces.
And actually, our earth has broken apart before.
A planet called theia is believed to have crashed into gaia, the early earth.
Theia was a planet the size of mars that some scientists believe crashed into our earth.
This collision is what could have caused the formation of our moon.
But if we factor in a huge planet crashing into our own, we would have to factor in the
event of a collision.
Lets say, for imaginations sake, highly advanced aliens from a distant galaxy used a gigantic
laser beam that successfully split our planet in half.
Lets not worry about the specifics too much, and dive right in.
If the earth split in half, Huge earthquakes would immediately shake the entire planet.
Power grids would go out and 7 billion people would be without electricity.
Horrific natural disasters would reduce the population of the earth to a fraction of what
it is now.
When this happens, There would be very few places you could hide that would guarantee
you safety.
I would imagine the halves of the earth that are furthest away from the slice that broke
the earth apart would be the safest places to be, or even in space.
If the earth were split in half, this would mean that The mantle and the earths core would
be exposed to space.
Which is a vacuum.
Our earth isn’t a nice smooth piece of jello, where if it gets cut in half, the two halves
remain in tact.
It’s a gigantic rock split up into many pieces, known as tectonic plates.
For this reason, Portions of the planet would be pulled out into space and the earth would
begin to lose its mass.
The water in our oceans would also spill out into space.
If there were any survivors after all the natural disasters, there wouldn’t be very
many, and they likely wouldn’t be around for very long because literal chunks of the
planet would continue to float out into space, and each chunk would heat up to unfathomoable
levels.
The good news is, over a long period of time, hundreds or even thousands of years, Gravity
would eventually pull the two pieces of the planet back together.
But before that, huge levels energy would be realeased.
The two chunks would become two molten pieces of rock that would gradually become spheres
thanks to the force of gravity.
So if there was any life left on earth after it was split in two, there definitely wouldn’t
be any while it was two molten pieces of liquid hot magma.
Eventually, the molten pieces would come together, to form a new earth.
But this time, the earth would be smaller, because of all the matter the earth lost into
space.
If theia really did crash into our planet 4.5 billion years ago, the same thing happened.
Our planet could have actually been much larger, but as a result of the collision, it broke
apart into two smaller pieces, one of them being the moon.
Gravity eventually moulded these pieces into spheres.
The good news is, its likely that the earth would still retain much of its organic matter
and After hundreds of millions of years, Life on earth would begin again, first, microscopic,
single cellular, then multicellular.
Eventually plants would grow, and life would get more and more complex through the process
of evolution.
Of course the life, it were to evolve to be intelligent, would have no idea that there
once used to be previous life forms on the planet.
Its as if a reset button was pressed.
Who knows, before theia crashed into our planet, there might have been an advanced civilization
like our own that was obliterated by the earth breaking apart.
There’s some food for thought, but now I open up the question to you, dear subscribers,
what do you think would happen if the earth split in half, let us know in those comments.
Before I wrap up this video, I’m going to respond to some comments from our video, what
if hitler came back to life.
Maria Teixeira – what if a solar flare hit earth.
Solar flares hit earth all the time actually.
Cipher – u guys make good videos.
Well thank you very much, I’m glad you enjoy them.
Soulayman elmathari – WHAT IS THE GODDAMN THEME MUSIC THEY USE.
We will never tell you.
mwhahahahaha.
Technical Calculator – this channel is getting funny now.
Just now?
Caman.
Oh wait, do you mean you’re laughing at us or with us.
I feel attacked.
Vladimir Putin – Are you running out of ideas.
People have bee saying that for 2 years and we are still here.
No vladmir, we are not running out of ideas.
But thanks for the concern.
