#DYK American astronomer #VeraRubin was met by skeptics in the 1970s when she proposed evidence for dark matter. She studied galactic rotation curves.

According to Newton's laws, when objects rotate around a common centre, the ones furthest from the centre move more slowly than those near it. Otherwise, the furthest objects would fly off into space.

Rubin's observations of stars in galaxies didn't match this. Either there is mass that we can't see or gravity behaves differently than we presently know. #DarkMatter is now widely accepted in the scientific community thanks to the work of Vera Rubin.

An incredible 85% of the matter in the #Universe is still “dark” to our eyes. We know it must be there, but don’t know what it is. #DarkMatter thread to follow soon... get ready😎

The first hints for #DarkMatter existence can be traced back in the '30s (#Oort in '32 and #Zwicky in '33), but the problem was not given much attention until the '70s. BUT, what was "the problem"? 1/
(In the picture is the Swiss astronomer Zwicky)
In a nutshell "the problem" was that:
1) if you believed in Newton's laws about gravity
2) and you trusted your data
--> there had to be some "hidden", "dark matter" to explain the data. 2/
