    Ive never heard of black holes suddenly expanding. Everything ive read js that they just very, very, very slowly dissipate through Schwartzchild radiation.

        What’s the “they” that you mean? The event horizon, the transition point where light can’t escape?

        That doesn’t sound like what they were saying. The actual “hole” supposedly remains infinitely small. And the event horizon radius would expand at a pretty slow rate as matter fell into the black hole. Exponentially smaller as it gains mass.

        So I’m still trying to understand in what case a black hole ever “expands rapidly”.

          Dude, everyone here has said they’re not experts. Idk what you’re expecting us to say.

            Dude, I’m expecting the most basic explanation of what someone meant by something they said. Claiming not to be an expert isn’t a good response when someone asks wtf you meant

            You said

            What starts from a very small condensed state, and expands rapidly while spinning in one direction? Black holes.

            I’m asking where you got that from, since it’s the opposite of anything ive ever heard about black holes and what almost anyone thinks about black holes.
