Are black holes hot or cold in their cores

Like most other planets have hot cores and they are very hot. What about the Black Hole type of planets?

Black holes are absolute zero, I think, which is like three hundred and something degrees below zero in celsius, or apparently so. The electron stops revolving around the nucleus of the atom, and collapses, which is why it's so dense. The truth is that nobody knows though. It's mostly guesses.

Black holes are the endstate of stars, not planets. A black hole will form if the mass of the stellar core that collapses is greater than three times the mass of our sun. Such a large collapsing mass cannot be balanced the same way smaller stars are balanced, and so the star collapsses to a singularity - a black hole. The force of gravity is so strong at this singularity that not even light can escape - hence the term black hole. There are complex theories about the nature of the singularity, and include the curvature of spacetime, and slowing down of time as an object approaches its centre. A black hole is observed by its interaction with other matter. Any matter falling into a black hole gains kinetic energy and heats up, becoming ionised and emits electomagnetic radiation. If the temperature exceeds a few million degrees then the material radiates as x-rays. To emit strongly at x-ray wavelengths, the temperature should be approximately 10^7 Kelvin

Black holes are not planets.
And they are an infinite temperature.

I don't think anyone knows that. Seriously.

Hold on, ima go check.
You know it's not too bad, a little on the cool side but overall it's tolerable.
