Jim_B:
Fermi’s Paradox notwithstanding, is it still obvious that there are advanced ET’s out there?
Notice I use the word ‘obvious’. And I put this question in GQ.
I’m not sure why you put it in GQ, since it obviously belongs in Great Debates. Rather than move this one, I refer you to an existing thread in that forum if you wish to discuss this.
There are lots of plausible hypotheses, that don’t contradict existing known data, for why we don’t see evidence of advanced ETs.
Why are we spending so long discussing a hypothesis (black hole clusters) that is nowhere near attaining that status?
Agreed.
And as mentioned upthread, and ignored, we have performed gravitational microlensing surveys.
To the extent that our galaxy could be littered with black holes, their size and/or distribution seem insufficient to affect most lines of sight …
