In http://www.hawking.org.uk/lectures/lindex.html Steven Hawkins says: "In an infinite and everlasting universe, every line of sight would end on the surface of a star. This would mean that the night sky would have been as bright as the surface of the Sun. The only way of avoiding this problem would be if, for some reason, the stars did not shine before a certain time." Now I am the last one to disagree with anything a man like Steven Hawkins says, but I´m having a difficult time understanding why what he says is true. Stars don't exist for ever, so the star density is limited, (I guess in fact that real star density is much lower than visible star density because many stars we see don't exist anymore, though there are also many stars around that we haven't seen yet.) Also the brightness of the light of a star goes down with distance, eventually the brightness is so low that it is no longer detectable from the background radiation. (right?) Adding everything up, my logic concludes that even in an infinite and ever lasting universe, the night sky doens't shine as bright as the surface of the Sun. I feel like the milky way should be shining that bright because almost every line of sight into the milkey way is ending up on a star... Especially close to the center of the milky way... but city lights are already lighting up the atmosphere so much you can't see the milkey way at all. Where is my logic wrong?
