30 years ago, Stephen Hawking arrived at an elegantly simple expression of black hole entropy:
S = c^3 A / 4hG
where
S = black hole entropy
c = speed of light
A = area of event horizon of black hole
h = Planck's constant
G = gravitational constant
However, this relationship has a disturbing implication: that when a black hole evaporates, swallowed matter and its associated information will be lost. This is a grave violation to the very foundation of science: cause-and-effect.
