From what I understand it then reaches a singularity and then evaporates and disappears which I never understood. How can it evaporate if nothing can escape? What I would be interested in is if it could tear the fabric of spacetime.
Evaporates? If it evaporates, how is there anything there...I suppose it could just tear a hole in space that everything get’s sucked into who knows where....kind of like universal drain plugs. Or which I think is more likely, black holes ARE STARS, and they do produce light, but we can’t see it....because the light cannot escape the gravity of the black hole, thus no light.
Two ways. One is always present as a quantum effect. The term "fuzzy black holes" means to conjure this up. At the edge, some particles will appear "on the other side" even though that contradicts classical physics.
The other mechanism is losing mass by losing energy by radiating heat into space. Not possible "today" (whatever "today" means on a cosmic scale) because the cosmic background radiation is still "too hot."
