👤 whose
Whose work first explained why galaxies move the way they do in clusters and superclusters?
Quick Answer
Vera Rubin’s galaxy rotation studies helped reveal that galaxies contain large amounts of unseen mass. That unseen component is now called dark matter.
The Full Story
Vera Rubin measured how stars orbit within galaxies and found that outer stars move much faster than visible matter alone would allow. Her work in the 1970s provided strong evidence that galaxies sit inside massive halos of unseen material. This invisible component is now called dark matter. Rubin’s observations became a cornerstone of modern cosmology because dark matter appears to shape the growth of galaxies and large-scale structure.
