I find the idea of an infinite amount of matter impossilbe to even imagine. Let alone the possibility that it all fitted into a finite amount of space at one point (the "Big Bang"). The whole thing gives me a headache, in fact, but if there were to be an infinite number of stars, then the light from them would have to cross vast distances and almost always be absorbed, deflected or reflected by various planets, stars and dust particles before reaching Earth, hence you wouldn't be blinded by the light from them. It's difficult even to look into the sky at night and point out the centre of the galaxy, despite the fact that the density of stars there is many, many times greater than at the edges.
