Hey Kyle.

So a question has been going through my head for a couple of years now and this is a bit of DBZ style type question.

Hypothetically, say one of Goku's enemies like Frieza came to Earth and instatnly zapped away a 10ft swath of Earth leading all the way down through the core out the opposite side, effectively cutting the Earth in two (hypothetically) equal parts.

Now there's a 10ft gap between the two halves of Earth. Due to the gravity of two halves, do they the come slamming back into each other at 9.8m/s? Does Earth pressure bulge itself out on two halves to meet in the middle? A mixture of both? Or do they float apart for longer essentially sucking Earth's atmosphere into the created gap?

Aside from smoking and drinking, what are the worst things I can do to my body that would make donation useless or less viable?
