There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...

The quest to reconcile quantum mechanics with the geometric description of space-time lies at the heart of modern theoretical physics. Quantum gravity seeks a framework in which gravity itself ...

Introduction: Theories That Do Not Input SpacetimeOne of the most fundamental questions in modern physics is, "What is spacetime?"In general relativity, gravity is described as the geometry of a ...
