Is there any place in the universe where someone can exist and not experience any gravitational forces? Not even far away from the moon in our solar system?

if you got a shovel and hollowed out Earth, and then went inside, the net gravitational force on you would average out to zero.

Hold on, so you are saying we would not experience gravity but the Newton law tells us that in reality there are still gravitational forces on us? Then why can we not hollow out other things for anti-gravity? What's to stop someone from hollowing out a huge boulder deep underground and floating inside it?

FROM the earth. What about the sun? What about the supermassive black hole in the centre of the galaxy?

tl;dr - no; if you're in the universe, you experience gravity

No. Your mom's mass will pull in even the most remote region of space.

Lmao.

I guess the Lagrangian points. They're places where the forces of gravity between two bodies cancel exactly.

Center of mass of the universe.

No, not really.
Consider this, You have mass. Therefore, you produce gravity. Even if it is so infinitesimal.... it still exists.
Therefore, as long as you have mass, there will be gravity no matter where you go.
And even if are incredibly far away from any other mass, gravity extends out nearly forever.

I can't exactly say it extends out forever. Because there may be a quantum limit to gravity - beyond which gravity is either 1 quanta, or 0 quanta. So there may be an outer limit to how far gravity can extend.
But it extends out really far away.

It would be exceptionally difficult (but maybe not impossible) to put yourself beyond the gravitational reach of everything else in the universe.

You don't experience gravity unless you're on the ground. You can experience tidal forces form extreme gravity, in the middle of no where in our galaxy there would be no tidal forces.

>> No.8881384

No, because gravity is not local

Are you retarded?

Go to the L1 point between the earth and moon, and you will experience microgravity that's so small that it would be hard to measure.

But gravity propagates at the speed of light, so the universe's center of mass would remain in such constant flux that impossible-to-track things such as quantum tunnelling may have net discontinuity effects on the order of parsecs.
