What if the Earth were Hollow?

What if there were a tunnel through the middle of the earth and you jumped in?

My dog keeps trying.

One does not simply dig a hole through earth.

Thank you for correcting me.

Look up Newton's shell theorem. The net force of gravity within a hollow sphere is ZERO no matter where you are in that sphere. You understand that mass and distance are factors, yet you didn't actually apply the logic. The AMOUNT of mass is important. There isn't all that much mass that is pulling you DIRECTLY to the wall. The vast majority of the mass (which you are farther from) is pulling you away from the wall. It always nets to zero, and has been proven mathematically by Newton.

Wait, if you were in the earth, you would be attracted to the nearest wall. Gravity depends on both mass and distance so the closes piece of the crust would attract you the most.

what if we upset the earth's stomach and it shit out lava

[Allister Hawkins]

Why is not " what if the earth was shallow" ?

[Zarnirox]

They're gonna shoot some aliens? :D

How does he do the animation? The stickman falling. What software is he using?

[Jeremy Wolter]

i accually live in a town called hancock... which is a copper mining town ... that same which tested the canonball thing

what happen if you use magnets, to try create like earth? Well of course you be shielded a bit, but it doesn't mean you block out the heat or cold which we will freeze or burn to death by the sun or darkness. unlike earth's gravity, magnets can't be purely the same, if it was then we will be pulled in that direction or be rip apart because our own body carry atoms. So magnets and earth's gravity good reason to be different. Imagine good god, we be all over the place in blood bath hitting wall
