Who discovered dark matter: Fritz Zwicky or Vera Rubin?
<p>It’s hard to believe, but the idea that the Universe was dominated not by normal matter <a href="https://en.wikipedia.org/wiki/Dark_matter" rel="noopener ugc nofollow" target="_blank">but rather by dark matter</a> — a novel form of non-interacting matter that’s completely distinct from protons, neutrons, and electrons — goes all the way back to 1933. For decades, the overwhelming majority of the leading astronomers and physicists dismissed the idea as being ill-motivated, and it gained very little traction on both the theoretical and observational fronts throughout the ’30s, ’40s, ’50s and ’60s. It was only with the novel results and improved instrumentation initially leveraged by Vera Rubin and Kent Ford, and then further developed by Rubin on her own, that dark matter was brought into the cosmological mainstream in the 1970s.</p>
