Olbers’ Paradox: Problem

“If there are so many stars in the sky, then the night sky shouldn’t be dark, right?”

Does this question make sense to you? This is called the Olber’s Paradox, named after the German astronomer Heinrich Wilhelm Olbers. It argues that if the universe is static (neither expanding nor contracting) and has infinitely many stars, then wherever you look at the sky, you should see a star. This suggests that the night sky should be as bright as that of daytime.

Let us watch Prof. Goto’s explanation of this paradox, and after this you will try to argue if this is correct or not.
