Suppose all matter in the universe is at absolute zero: Is gravity still in tact?

Question

Also, would it still be matter? Or would it take a different form? What would that look like? (If it had any visual appearance at all)

Answer 1

Actually there is MORE gravity because stuff at 0 kelvin is heavier

Answer 2

according to einstein, gravity is affected by mass. so answer: YES

Answer 3

You can't reach absolute zero, you can only approach it.

At very close to zero, nothing is moving. But gravity is still in effect, and the planets are still in orbit around a "sun" that is just a solid sphere of frozen H and He.

The fact that the planets are moving implies that there is still energy, and not at absolute zero.
