Galileo Galilei
In 1924, American astronomer Hubble showed that our galaxy is not the only one. He calculated the distances between numerous galaxies, and in the process discovered the red shift—meaning light from distant galaxies was on the red end of the light spectrum, and as such must be moving away from us. In 1929 Hubble changed everyone’s understanding of the universe for good by revealing that the universe is expanding, and therefore that it could have all started off in one place—thus creating the idea of the big bang. This meant Einstein’s idea of a cosmological constant, or a kind of anti-gravity force, was inaccurate.

Quotes
It is an interesting reflection on the general climate of thought before the twentieth century that no one had suggested that the universe was expanding or contracting. [...] this may have been due to people’s tendency to believe in eternal truths, as well as the comfort they found in the thought that even though they may grow old and die, the universe is eternal and unchanging.
