This Day in Science History - March 2 - Heinrich Olbers
March 2nd marks the passing of Heinrich Olbers. Olbers was a
German physician and amateur astronomer who devised a simple method to
calculate the orbits of comets and discovered two large asteroids, Vesta
and Pallas. He also believed the asteroids were remnants of a wrecked
planet that orbited the Sun between Mars and Jupiter.
Olbers is also known for the question "Why is the night sky dark?". If you assume that the universe is infinite and filled with stars, you should see light from stars in all directions and the night sky should be as bright as daylight. As we all know, the night sky dark with many points of light.
This question is known as Olbers' Paradox and had no simple answer. The Big Bang Theory tries to answer the question by stating there is a finite number of stars and the universe is constantly expanding.
