Evidence for quantum gravity? : r/AskPhysics - Reddit

Currently, we still lack definitive evidence of quantum gravity. While many theories exist, none have been definitively proven.

Might There Be No Quantum Gravity After All? - Physics Magazine

A proposed model unites quantum theory with classical gravity by assuming that states evolve in a probabilistic way, like a game of chance.
