Q. Whose paradox asks why the Sky is not ablaze with starlight if the Universe is infinite in extent and uniformly filled with stars?
Solution:
The apparent paradox that if stars are distributed evenly throughout an infinite universe, the sky should be as bright by night as by day, since more distant stars would be fainter but more numerous. This is not the case because the universe is of finite age, and the light from the more distant stars is dimmed because they are receding from the observer as the universe expands.
