Event Details
In 1929, astronomer Edwin Hubble published data showing that distant galaxies are moving away from Earth at speeds proportional to their distance. This relationship is known as Hubble's Law. It provided the first observational evidence that the universe is expanding, leading to the development of the Big Bang theory.
