What is Olbers' Paradox regarding the night sky's appearance?
Answer
The stark conflict between the expectation of a uniformly blazing sky and the observed profound darkness.
Olbers' Paradox highlights a fundamental contradiction arising from the assumption that the universe is infinite in size and eternal in age. If these assumptions were true, every line of sight from Earth should intersect the surface of a star, leading to the entire celestial sphere shining with the overwhelming brightness equivalent to the surface of the Sun. The observed reality, however, is a profoundly dark night sky, which directly contradicts this expectation based on simple geometry and uniform stellar distribution.
