Quantum gravity is the 'holy grail' of physics. This problem, or mystery still remains unsolved today, due to the conflict and contradiction between two major pillars: Quantum mechanics & relativity. In this work, we tried integrating something even bigger. We added thermodynamics into the play, and what we found is potentially groundbreaking for such discovery. We have found the perfect sweet spot, where both theories on macroscopic and the microscopic world fits together and shake their hands.
