Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general ...

Physicists are facing a paradoxical situation. On one hand, they are searching for a fifth fundamental force that could ...

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all. Instead, it could arise from entropy, a measure of disorder. The theory, ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and reveal the ultimate fuzziness of time ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of gravity ...

Post-spacetime physics refers to the idea that our familiar 4D spacetime is not fundamental but emerges from deeper ...
