Black holes, these extreme cosmic entities, might well hold the missing clues to solve one of physics' greatest mysteries: the unification of general relativity and quantum mechanics. For over a ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...
