The true answer is that we don't know. There's no deep fundamental theoretical reason that it should. We also don't know why inertial mass is the same as gravitational mass.
Weight would not exist without gravity.
If there is gravity there is weight. So the weight exist only when the gravity exist.
Yes. Gravity is a property of mass.
If the earth had no gravity it follows that gravity would be absent from any mass. In the absence of gravity life would not exist.
Without gravity, it is doubtful that the universe as we know it would exist at all. At the very least, galaxies, stars and planets would be unable to form. Worse still, without stars there would be no heavy elements and it is unlikely that life would exist.
Weight would not exist without gravity.
The earth doesn't spin because of gravity, and gravity has not ceased to exist.
If there is gravity there is weight. So the weight exist only when the gravity exist.
Yes. Gravity is a property of mass.
There are likely places in the universe where there is very little gravity, but it is probably impossible for no gravity to exist somewhere. There is very probably gravitational influence just about everywhere.
No, It exist everywhere, but it does very.
yes
Gravity exists everywhere that mass exists, so the answer is yes.
well we would be dead because, gravity is what keeps us on the ground.
only when there is gravity present
If the earth had no gravity it follows that gravity would be absent from any mass. In the absence of gravity life would not exist.
Yes, but so does internal pressures. (Which wouldn't exist if gravity wasn't present.)
