Re: Damn you Brain, why you no genius?
One of the late great Jack Williamson's later great short stories had trust in Hawking radiation going wrong as a central plot point.
Someone makes a mini-black hole in containment, it falls out, gains mass ...
Doesn't evaporate.
I cannot recall the title, still have it, but it is in a box right now.
On the concrete level, I cannot imagine the conditions for mini black holes that evaporate through Hawking radiation to form.
