To explore the subtle aspects of this question, we will consider it in the context of Albert Einstein’s general theory of … Read more Does light accelerate when approaching the edge of a black hole?

Does the matter inside a black hole have temperature and density?

Does the degenerate matter inside a black hole have a temperature, or is it so compact it’s functionally at absolute zero? Also, if event horizon scales with mass, does matter inside the event horizon have a specifiable density? Thanks for a very intriguing question. The basic answer is that no one knows and that it … Read more Does the matter inside a black hole have temperature and density?
