This is an original Hyperstar (no collimation or camera angle adjusters) and SX H9C OSC CCD image of the Coma cluster of galaxies. This galaxy cluster was made famous by Fritz Zwicky who studied the cluster, and by applying the virial theorem to star motion in the galaxies he deduced that there must be some form of Dark Matter present.
There are a number of people attempting to re-write history by stating that Vera Rubin discovered Dark Matter during her work in the 60s and 70s where she also applied the virial theorem to star motion in galaxies. Unfortunately she was around 30 years late in coming up with that one.
What a snide, inaccurate view of science. Yes, Zwicky discovered missing mass in the coma cluster by applying the virial theorem. But Rubin’s galactic rotation curves were no less important in our understanding of dark matter and its significance in galactic mass distribution and structure. This is how science progresses – Rubin developed a new measurement technique that supported Zwicky’s work. There is no need to set them against one another or diminish her work in order to hold up Zwicky’s place in history.
In your own words you confirm that Rubin added nothing to Zwicky’s observations from decades before regarding the observation of stellar motion in the outer regions of galaxies implying the existence of dark matter. My unbiased observation was therefore neither snide nor inaccurate, unlike yours.
