Where do black holes come from?
- Answer: GRAVITATIONAL COLLAPSE
- The star apparently has to go on radiating and radiating and contracting
and contracting until, I suppose, it gets down to a few kilometers
radius when gravity becomes strong enough to hold the radiation and
the star can at last find peace. -- Eddington, 1935
- I felt driven to the conclusion that this was almost a reductio ad absurdum
of the relativistic degneeracy formula. Various accidents may intervene to save
the star, but I want more protection than that. I think there should be
a law of Nature to prevent the star from behaving in this absurd way.
- Eddington's supreme authority in those years effectively delayed the
development of fruitful ideas along these lines for some thirty years.
-- Chandrasekhar, 1980
Black Holes form on 2 scales:
