It is a scandal that Edwin Hubble, clearly the most prominent observational astronomer of the 20th century, who discovered intergalactic space and expansion and hence big bang, never got the Nobel prize. Why? The prize committee, the Swedish Academy of Science, had the view that “Astronomy is not physics, and there’s no prize for astronomy!” An old view that astronomy is just a branch of mathematics, the study of dots moving across the sky. They better not miss awarding LIGO, and since people have been on to this for 50+ years, they cannot wait too long.
