If the earth were a hollow shell and you were inside it would there be gravity acting on you or would you be?

Question

weightless?

Answer 1

If you do the math involved in the shell theorem, you discover that the net gravitational force on you from this hollow shell would be zero. If this hollow shell earth were to suddenly disappear, you would experience no change in gravitational force. But you would still experience gravitational force from all other masses in the universe, primarily the sun and the moon. You would stay in an orbit around the sun that is perturbed somewhat by the moon. But it would be the same orbit as the earth, so your experience would be weightlessness, and if you started motionless in the center of this shell, you would stay there.

Furthermore, according to the principle of equivalence in relativity, since you are moving freely in response to those gravitational forces, if all the rest of the universe suddenly disappeared, you would experience no change in gravitational force.

Answer 2

Oh costly. there is 0 gravitational tension everywhere interior a hollow around shell. (there is, in actuality, a generalization of this theorem, proved through Newton: there is 0 gravitional tension everywhere interior a homeid, it incredibly is a shell shaped through 2 comparable ellipsoids.) The Earth is, of path, no longer hollow. yet once you have been someway able to make a hollow chamber based on the middle of the Earth, you are able to waft weightless everywhere interior that chamber. "could there be gravity interior it?" The gravitational skill interior a hollow shell isn't comparable to the gravitational skill outdoors it. This has observable effects: to illustrate, a clock interior the shell could tick at a distinctive fee from a clock some distance from the hollow shell. So in that experience, there remains gravity, whether there is no gravitational tension.

Answer 3

You would be weightless.

At any point inside a uniform spherical shell, the gravitational pulls from all parts of the shell cancel out and there is no net pull anywhere. Even if you were touching or standing right on the inside surface of the shell, you would feel no force or pull. The mathematics behind this is rather complex, but if you're interested you can follow the link below to learn more.

A person on the outside of the shell would still feel a gravitational pull.

Answer 4

If there was no other significant gravitational force acting on you and if it can be assumed that the earth's crust is evenly massed across it's surface area, then the gravitational pull from all the sides would cancel each other out and I believe you would float in the middle, just like that. However, before that happens I'm pretty sure we would fall out of orbit and wander aimlessly through space freezing into oblivion due to lack of sunlight, but no mind :D.

Answer 5

Gravity acts upon every object in the universe; th emoon is pulling on you now. Besides, even if the Earth were a hollow sphere, it would still have more mass than your body so it would also have a greater gravitational field

Answer 6

if the earth was hollow then the sun would of pulled the earth into it because the sun keeps us in orbit. gravity will be there but not much at all
