We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged.

Einstein’s general relativity is an exceptional theory of gravity that has been proven correct time and time again. Quantum ...

Astronaut Barry “Butch” Wilmore is “doing good” but is having a “rough” time adjusting to gravity after his prolonged nine-month stint in outer space, his daughter revealed. Daryn ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the matter field and the geometry. Credit: Physical Review D (2025).
