Can 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?

the universe doesnt expand as it gets colder… it gets colder because it expands. when it expands, imagine all the heat currently distributed throughout the universe being spread out more and more. you thought backwards
at absolute 0, kinetic energy ceases. that doesn’t include electromagnetic radiation (light, heat, gamma radiation), which is entirely different.
gravity is the force of attraction between two bodies of matter. at absolute 0, those bodies’ densities would increase (not their mass) so their escape velocity would actually increase. it would be harder to lift off from the surface of the earth if it was compressed to half of its original volume, even if its mass stayed the same
hope I helped.

you cannot freez light because absolute zero would be better defined as the point at which all PARTICLE motion stops not all mothion photo rays which make up light can still do their thing

If absolute could be reached it would cause the disappearance of all natural forces.
