My point is slightly different from Fermi's. Fermi was trying to answer the question of whether there is life in other parts of the galaxy. He assumed that if there were, then they'd be able to get here. So where are they?
I assume there is life out there. It's not quite so clear to me, though, that they can get here. Even getting to the nearest star would take centuries with any conceivable advances in science that we might imagine. And certainly, there is no life in that solar system, since it's a double system.
If this guy is right, though, then clearly they could get here, so where are they?
"If this guy is right, though, then clearly they could get here, so where are they?"
If Felder is right is not indicative that they can get here. As a minimum, they must know of Felder's equation. Like you said in your post, life may be out there but they don't know how to get here.
