A black hole is the name given to any object whose gravitational pull is so powerful that the speed required to escape from it exceeds the speed of light. Therefore, anything that comes too close to a black hole will be unable to escape from it.
There are countless black holes in the universe. They are quite common objects. There is a super-massive black hole at the center of our galaxy – within or near Sagittarius A – and presumably at the center of all galaxies.
Normal stellar black holes (formed from collapsed stars) are quite plentiful within our own galaxy. Stars that are about 20 times as massive as our Sun are likely to end their lives as black holes.
Black holes are very dense and massive objects. Their gravity so powerful that the laws of nature within them behave differently, and we still do not know all about what the conditions within a black hole are. However, it is not likely that there are fires burning within them in any way that we could possibly define fire. What we know about black holes scientifically would not predict the existence of anything like fire within them. Indeed, it seems that the inside of a black hole might be quite cold.
There is absolutely no reason to believe that Hell is located inside a black hole. That is a claim that has no evidence for it, neither from the Qur’ân and Sunnah, nor from science.
Hell is a matter of the Unseen. We only know about Hell what Allah informs us about it by way of revelation to His prophets (peace be upon them). Its location is a mystery to us.
May Allah protect us from speaking about the matters of the Unseen without knowledge.
And Allah knows best.
