Now what I'm about to say may sound like a sort of speculation but not in the typical bad way. Now we have a black hole in universe somewhere.(Doesn't matter where for my theoretical purposes) Now we know that once a big star looses all or most it's fusion elements and some of it's mass that went off as energy through that fusion , it's left with no fusion heat/power and alot of mass , now it collapses to a black hole.Ok we cannot undo this. Now let's imagine a huge hydrogen gas cloud in the order of mass similar to a large star approaches the black hole.Now the black hole "sucks" the matter (hydrogen gas) in. Black holes do evaporate via hawking radiation but if a black hole with the mass "x" would suck in hydrogen gas that is heavier than the star from which it formed (assuming the black hole hasn't been around long enough to build up it's mass from other infalling matter) Now wouldn't that mass of hydrogen under the immense pressures of a black hole start off a fusion reaction faster than it could evaporate via hawking? P.S. I know we really don't know what happens at a singularity once past event horizon as there is no "light" anymore to show us what's going on but theoretically if we believe that all the matter that goes in can't just disappear but rather builds up in the singularity wouldn't that make the hydrogen to build up and cause fusion to start and cause the singularity to expand? Ok maybe another theoretical approach would be asking what would happen if we would put an atomic bomb with mass higher than the mass of the black hole with a timer set in a way that it explodes after it has passed through the event horizon? Or maybe the gravity beyond the event horizon is so strong that it could stop the explosion of a atomic or H bomb or whatever force that is rapidly expanding , because if not even light cannot escape the horizon then i guess all other matter too exploding or not would still plummet towards the singularity once past the event horizon?
