Part 2 – Astrophysicist Vera Rubin worked with fellow researcher Kent Ford in the ’60s and ’70s. Together, they studied galaxies – and wondered why things like stars were able to move so rapidly without falling apart.

Rubin’s calculations led her to surmise that there was an invisible force at play called “dark matter” – an idea first proposed by Fritz Zwicky in the 1930s. Fellow astronomers were initially reluctant to accept her theory, but soon physicists like Jeremiah Ostriker and James Peebles provided further framework, which cemented dark matter’s place in science.

The evidence Rubin gathered was extraordinary, and ushered in “a Copernican-scale change in cosmological theory,” according to The New York Times.

But Rubin never received a Nobel Prize.
