In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

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) ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

Noncommutative Quantum Field Theory represents an ambitious extension of standard quantum field theory that incorporates a fundamental noncommutativity in the structure of spacetime. In these models, ...

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 ...

The nature of gravity — and whether it can be reconciled with quantum mechanics — is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...
