That's not the reason.
Google "Olber's Paradox"

Nope, for same reason it's not true for light, which has nothing to do 
with dust absorptoin.

EVENTUALLY all would hit a black hole IF the universe is unbounded. But 
that might take quite a bit longer than the age of the universe. MOST 
neutrinos that have been emitted sometime in the last 13.8 billion years 
have not traveled far enough to hit a black hole.

But let's suppose the universe is bounded. In this case, if you keep 
going straight in some direction, you'll eventually end up right where 
you started. Or at least you'll end up in some place very near to where 
you started. It's like traveling straight ahead on the surface of the 
earth, veering neither left nor right, and you're not sensitive to the 
curvature of the surface. Now ask, "If I head in some random direction, 
will I eventually run into a volcano." Well, maybe. It might not happen 
on the first pass around the earth. Maybe it happens on the 3978th pass 
around the world, each time your path being a little different than what 
it was before. But it's also possible that you NEVER run into a volcano. 
Because there are only a finite number of volcanos on the earth, and 
it's possible to pass an INFINITE number of times over the surface of 
the earth and there still be some places you never get close to.
