It doesn't make sense for me to repeat what others have already said dozens of times. Also, you don't need to know how supersymmetry works to understand what I am saying. (And it's not related to gravity.)

'Hawking radiation' appears include whole galaxy main discs! 'Basic GR' also fails for space probes, needing on-board AI for regular course corrections as they're needed in real time.

If none, we have 'grey' or 'white' holes, but I agree to a divorce is now easier to sell than 'no black holes'.
