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 ...

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

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 ...

A new study by researchers from the University of Barcelona and the University of Padua challenges one of the core ideas of modern cosmology: that the Universe began with a rapid expansion called ...

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 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, ...

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 ...

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 ...

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

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...
