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.

Her approach derives gravity directly from quantum information theory, potentially solving deep mysteries like dark matter and black holes.

Why Gravity Resists Unification The Standard Model is built on a framework called quantum field theory. This theory merges classical field theory, quantum mechanics, and special relativity.

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent ...

A new study shows quantum entanglement follows universal rules across dimensions using thermal effective theory.

The universe is quantum, and unlike the other fundamental forces — the electromagnetic, the weak and the strong nuclear forces — which have been described within quantum field theory, what we know of ...

Scientists have used cutting-edge research in quantum computation and quantum technology to pioneer a radical new approach to determining how our Universe works at its most fundamental level.

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation value of the gravity quantum field. (CREDIT: Aalto University) ...
