If that was 3.5 billion years ago...does it exist today?

18 Billion stars may be headed our way?

I believe so. Supposedly, black holes do eventually evaporate through the Hawking radiation process, but it takes an incredibly long time. IIRC, a googol years, 10¹⁰⁰ years on average for a stellar mass black hole??? Well, I think I remember seeing that somewhere. At any rate, 3.5 billion years is the blink of an eye for a black hole.
