Between dark matter and dark energy it is very likely that there are barriers to interstellar travel besides simply the distance and the speed of light as an absolute.

Everyone loves to speculate on far out ways of getting to the stars in short order but you get little or no speculation on hazards which we may not know about.

Where is everyone? Safe at home.

P.S. It is my opinion that Fermi was joking.
