does absolute zero overpower the power of gravity?
I thought of this because as the universe gets colder it keeps expanding / doing the opposite of what gravity would make it do.
And imagine if a black hole was put under absolute zero and there was zero gravity, even if this is done on a micro-blk-hole this could show us how blk holes work and maybe look like inside?
lastly absolute zero is when all kinetic motion stops/ceases to exist, does that include light? does it just freeze too?

I don’t think you know what you’re talking about
What do you mean by “overpower”? A black hole is caused by a rip in space-time and gravity is caused by warps in space-time. These are forces, absolute zero is not a force it is an occurence.
If absolute zero is applied to a black hole then why would the warps leave and cause zero gravity? Obviously not.The only way that would happen is if absolute zero destroys mass.
Kinetic energy is the movement of matter particles in an object, light is composed of photons not matter so it would not include light.

Absolute zero effects the bonding of atoms and molecules and the motion between them. If you read up on super conductors, then you will run across a theory that electrons would travel through a conductor with no resistance at absolute zero. So blows the theory on everything going to a sudden halt at absolute zero. Gravity can be predicted by Newton’s formula, but no one knows what makes it tick. As of yet, no one has made any connection between gravity and temperature. It does not matter if it is the hot gases from a star, or the cold dead rock in space, gravity does bend time- space in a predictable fashion.

If there was zero gravity, you would not have a black hole. Because of the intense gravity of a black hole, you cannot get data out of it because even light cannot escape. Otherwise it would cease to be a black hole.
Absolute zero is correctly stated as the point at which matter ceases to have kinetic energy. This means that the particles stop moving, and the quantum mechanical effects become macroscopically important. Each particle can no longer distinguish its own wave function from the neighbors, and all of the atoms dog pile onto each other, creating what is called a Bose-Einstein Condensate.
The atoms ignore the exclusion principle, because they can no longer “see” who is in what state, so they all occupy the same quantum state.
On freezing light: that is a very interesting question. Scientists have been able to stop light completely without having to dramatically lower temperatures anywhere close to absolute zero.

you should be more specific on what you mean by “over power”. First you should know that absolute zero is a theoretical construct. It can be shown from the laws of thermodynamics that it is impossible to achieve absolute zero, just like it is impossible to achieve 100% efficient engines. Check out wikepedia to get you started.
Also even matter would not completely stop at absolute zero. Particles have their ground state, and they will always have that minimum energy. This comes from quantum mechanics.
It is important to remember light doesnt have kinetic energy, since it is not a physical particle. However, you can read more about slowing down light in the last link.
And to answer your question, well you will just have to be more clear about what you mean by overpower.
