Original: "Hawking area law in quantum gravity"
Black hole collisions detected by LIGO are weeding out many quantum gravity theories.

Black hole collisions not only produce gravitational waves but also serve as a rigorous test for the very fabric of the cosmos. Fresh LIGO data is forcing quantum gravity theories to play by a simple rule: the total event horizon area cannot decrease – and this cuts out many complex constructs.
🎯 If the horizon area could shrink, you could endlessly extract energy from a black hole – but the universe's design forbids it.
S = \frac{A}{4}
S is the black hole's entropy, A is the area of its event horizon
