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.

The theory also builds upon well-established principles in quantum field theory. It borrows from the Dirac-Kähler formalism, which has gained traction in lattice gauge theory and network theory.

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

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

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 ...

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) ...
