as for the challenge i was giving, here ill put it simple with the number of stars that are out there or even in our galaxy why isn't the night sky way brighter then it was, cause realistically at and point you look up at in the sky there are probably 5 or 6 stars in your line of sight. and if space is empty there should be nothing to prevent the light of those stars from reaching us. So why is the night sky doted with stars NOT jam packed with them?

I know this is an old post, but do you live in a desert or in a city? Typically, if you live in a city, you can only see the brightest stars (ones closest to us) due to the city lights. Even if you shade your eyes, you can still only see a few stars. Take a trip out to the desert where it's pitch black and you can suddenly see all kinds of stars. Hell, you don't even have to go out to the desert, just go anywhere far enough from the city lights and you'll see them.

My point is that the night sky is jam packed with stars, you just can't normally see them unless you live in some remote area because the sky is lit up from the city lights. You also have the atmosphere to deal with, but your average astronomer can't really get past that. This is why telescopes are placed out in the desert and why NASA has been putting telescopes into space since the 90s.
