What If I Drilled A Hole In The Earth And Jumped In?
Let’s start off by saying that if you travelled around the earth in an aeroplane, you would have to cover
12,450 miles. If you jumped through the earth you would only have to cover 7,900 miles. The real
question is, What if I drilled a hole in the earth and jumped in?
Starting The Hole From America
Well, imagine you started off in America. If you managed to jump through the hole and survive, you
would end up in the deepest parts of the Indian ocean! and don’t be expecting a water slide experience either!
So let’s get into it. Depending on where you started drilling you can expect 20-40 miles of continental crust. After that, you will have to then get through 2000 miles of the earth solid core-mantle. Yes you heard right, 2000 miles!
After getting this far (who could have imagined eh?!) you will then reach the earth outer core. Liquid iron burning at around 10,000 degrees Fahrenheit! (which may I add is around the same temperature as the surface of the sun)
Now providing you have made it this far, you will now be faced with the brutal moon-sized inner core that’s entirely liquid. (scary right) Once you finally get to this stage, you then have to do all the above again!
How Long Would It Take?
So how long would this take? Well, its estimated at around 42 minutes. How you ask? well, the answer to that is gravity.
Gravity is pulling you towards the earth at a force of around 32 feet/per second squared. Now as you jump down the hole, you will speed up by 32 feet for every second you are falling. At about halfway to the core of the planet, you will now be travelling at an estimated 15,000 miles/per hour. Finally, once you reach the centre of the earth, you would be travelling at 18,000 miles per hour. (which is really really fast)
So you managed to make it all the way, well better hope someone is ready to catch you, because if not you would fall back down the hole and repeat the cycle! (Now that would not be a nice experience)
