These include: loop quantum gravity, causal sets, consistent discretizations etc. The problems with quantizing gravity basically all boil down to the fact that standard quantum field theoretic ...

Professor Oppenheim, along with Professor Carlo Rovelli and Dr. Geoff Penington, leading proponents of quantum loop gravity ...

Loop quantum gravity (LQG), co-developed by Rovelli, dismisses time as fundamental. The Wheeler-DeWitt equation describes a timeless universe shaped by causal interactions. Rovelli compares ...

Two recent developments suggest how familiar properties of gravity and matter may emerge from the quantum geometry that underlies loop quantum gravity. In everyday situations, and even in current ...

A century since Werner Heisenberg changed the course of physics, five of the world's leading physicists examine the greatest ...

The basic problem in formulating a quantum theory of gravity was already recognized ... most likely do not extend beyond the two-loop order for generic pure supergravity theories.

Do aliens exist? Carlo Rovelli, a founder of loop quantum gravity theory and author of the best-selling book "Seven Brief Lessons on Physics," says it's an easy question. "There is so much space ...

While some attempts to give string theory predictive power are underway, many physicists are looking elsewhere. Whether in the form of loop quantum gravity, causal dynamical trangulation or ...
