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.

Space is pretty much just empty space. There isn’t a whole lot of anything going on for most of it. Just as an example the asteroid belt is a fairly dense region of space. Dense enough to get it’s own name specifically because it’s the most likely place to find asteroids. Asteroids in the belt are also hundreds of thousands of miles apart from each other. If you you where to fly through it in a rocket, there is a good chance you don’t see anything unless you where flying to a specific asteroid. The rest of space is even emptier. Just void.
