#428 – Sean Carroll: General Relativity, Quantum Mechanics, Black Holes & Aliens
Sean Carroll
The dark matter, super important to emphasize here, you know, it was hypothesized at first in the 70s and 80s, mostly to explain the rotation of galaxies. Today, the evidence for dark matter is both much better than it was in the 1980s and from different sources. It is mostly from observations of the cosmic background radiation or of large-scale structure.
