Noun
(quantum mechanics) A branch of theoretical physics aiming to unite quantum mechanics with general relativity.
(quantum mechanics) The gravitational force modeled as a quantum field.
Synonym: quantum gravitation
Cornelia would not be altogether surprised if she saw the grazing cow start tap dancing, lap dancing, or whatever quantum gravity might cause cows to do. João Magueijo
Whether you can go back in time is held in the grip of the law of quantum gravity. Kip Thorne
I argue that the best strategy for understanding quantum gravity is to build a picture of the physical world where the notion of time plays no role at all. Carlo Rovelli
I was joined by Carlo Rovelli, and we were able to make a full-fledged quantum theory of gravity... This became loop quantum gravity. Lee Smolin
Combine general relativity and quantum theory into a single theory that can claim to be the complete theory of nature. This is called the problem of quantum gravity. Lee Smolin
We detect light and particles that have traveled billions of light years on their way across the universe to us. During the billions of years of travel, very small effects due to quantum gravity can be amplified to the point that we can detect them. Lee Smolin
