But, I’m conflicted, if a star collapses and creates a singularity with an event horizon, but then blasts radiation out until there is no singularity or event horizon, shouldn’t there be some kind of evidence left of it’s prior existence? Where does this radiation go? Out? How far?

Beats me - I find it ever so comforting at times like these to admit to being a dumb redneck. But the OP makes sense to me - If it is massively discharging mass, how then can it be accruing mass, or even sustain the mass necessary maintain a singularity? Anyway, the idea that something as massive as our sun could become so dense as to fit in my pocket has always been beyond comprehension.

And why, if a singularity is formed, doesn't it's massive mass simply discharge out the tail of the black hole anyway?

Black holes have tails?
