Eli5: Shouldn’t light from distant stars and galaxies appear to be continuously blinking by tons of space debri constantly moving between it and us through the Billions or year?

Hopefully the question makes sense. But it seems like we are always getting such great photos of these objects. You would think that one day you may be able to see a galaxy; while the next it may be completely obstructed by another object that is closer to earth but still thousands to millions of light years away.

The same reason a flashlight doesn’t blink from the particles of dust moving through the air. Even over large distances, they’re too small to make a visible difference.
