Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e., points where the laws of physics break down. Identifying how ...

Physicists have found a new mathematical way to connect Einstein’s description of gravity with ideas from quantum physics.

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e. points where the laws of physics break down. Identifying how ...

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a property that emerges from some deeper physical interaction. This emergent ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

A proposed model unites quantum theory with classical gravity by assuming that states evolve in a probabilistic way, like a game of chance. Physicists’ best theory of matter is quantum mechanics, ...

Somewhere between the microscopic realm of elementary particles and the macroscopic world of human beings, something strange happens: The rules of quantum physics, which work so exquisitely for tiny ...

Before determining the correct quantum theory of gravity, researchers need to know if gravity is actually quantized. Experiments testing that assumption are now being developed. Quantum fluctuations ...
