It's AumSum Time.
What if we Dig a Hole through Earth and Jump?
Then we would land on Pandora.
Oh AumSum.
Firstly, the atmospheric pressure will crush us.
Why?
Because once we go about 40 miles down, atmospheric pressure increases.
By about 1000 times than that at the sea level.
Secondly, no Fire Suit will be able to help us as the temperature.
At the core of the earth can reach about 10,800 degrees Fahrenheit.
Thirdly, there is a very high probability that once we reach the other side of the earth.
We would fall back again because of gravity, thus we will keep on oscillating like a Yo-Yo.
Lastly, even if we were lucky enough to survive the journey.
There is a very good chance that instead of safely landing in a country.
We would end up in the middle of an ocean.
