Olbers' paradox reckons that the sky should be blazing bright if there is an infinite number of evenly distributed stars (galaxies). the argument is something like in every direction that you look there would be a star. so the sky would be blazing bright. but even if there were an infinite number of starts in an infinite space. wouldn't the foreground stars be blocking the light from the infinite starts behind them? so for example if I looked at Sirius, I would only see Sirius and not the infinite stars behind Sirius, so that point in the sky would only be as bright as Sirius.
so another way to put it is, wouldn't an infinite number of stars cast an infinite number of shadows? and would there be more shadows than stars ( so there would be aleph 0 stars and aleph 1 shadows)?
and how seriously can we take Olbers' paradox?
