Entropic Gravity
Gravity is weird. On the face of it, it seems to directly contradict the second law of thermodynamics, that overall entropy in the universe must increase.Entropy generally involves "spreading out." It eliminates gradients, it doesn't fill them up. It is weird that there is a way to increase overall entropy by bringing diffuse parts together.Despite the term "entropic gravity", I still don't understand how this or other versions of gravity do not violate the second law. Does anyone here?
