Gravity just holds things down on Earth. It doesn't stop life in any way.
No, but the centre of gravity need not be inside the object. Not unless Gravity is not a variable. But it is not possible for an object to not have a center of mass.
As of now, manipulating gravity is not possible with current technology and scientific understanding.
no
It is possible if you get a machine that gives you more gravity.
No. We cannot alter gravity.
It is not possible for life sustained by OUR PLANET to exist on Jupiter. Is it possible that there is another form of life that can survive on Jupiter? Sure...its possible. There hasn't been any evidence indicating life on Jupiter.
Yes, it is possible to create artificial gravity through methods such as rotating spacecraft or using centrifugal force to simulate the effects of gravity.
No.
Yes, you can fight gravity. We all do it everyday. You just cannot win when you fight gravity. Gravity will be there no matter how you fight it.
no...cuz we live in a world where theres gravity
Digestion is not dependent on gravity. Astronauts do fine in space.
Energy cannot be made or destroyed, but gravity is possible because slows down universal expansion.
