While I doubt that explanation will hold, it is true that cosmological distances are where we should be looking for ET civilizations, as at those distances one can avoid the Fermi argument (although such a discovery would be pretty firm evidence we'll never achieve FTL travel.)
- andrewflnr 2y agoI don't know, cosmological distances might be too early for biological life to form and evolve intelligence and expand across galaxies. My understanding is that there weren't necessarily enough of the basic chemicals of life formed until relatively recently. (Phosphorus particularly is a problem, I'm less sure about the others) And doing anything visible across light years also takes a long time, especially if FTL is impossible, which it almost certainly is.
- pfdietz 2y agoThat's all true, to some extent, but at least it's not ruled out by Fermi.
