Dear PBS: It's "hole," not "whole."  Geez.

[PBS]

Neil deGrasse Tyson is teh WIN ^^

[McIntire4NC]

What if he took a ladder down to the exact center then jumped off? Would he just bob about the center, or would he fall in one direction?

[XxMineYourOwnCraftxX]

wouldn't you get stuck in the middle after lots of trips down and up?

[krash1046]

That's a good question

[clokedbigman]

@GHOSTTOYS i have no idea what your talking about

[GHOSTTOYS]

@KirbSleep that beach ball test take place on earth not in space so the gravity from the planet will act on the result

[GHOSTTOYS]

@clokedbigman well actualy i have ask this same question and i came with an answer , impossible or there is a paradox because if you jump in the hole there is a holle under your feet so there is no mather under you to create gravity , only the wall can attrack you .. pretty sure you will fall on an angle till you touch a wall or there is some thing else then matter that create gravity on the planet ..

[clokedbigman]

@apspacking well lets say you manage to get exactly in the center of earth...gravity would probably be pulling you in every single direction

[apspacking]

If Gravity is the curvature of space and time, what dose it do in the middle of the Earth?

Right before he jumps into the hole, he puts on a pair of Harry Potter quidditch goggles!!!Look them up on Amazon or simply on google images!!I noticed because i own some myself!!!:D

@vivalaryan54 His inertia. Objects naturally want to keep doing what they're doing until an outside force acts. He wouldn't slow until gravity decelerated him at the same rate he was accelerated.
