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 ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a ...

Scientists are diving into the deep sea to study one of the universe’s biggest mysteries—quantum gravity. Using KM3NeT, a ...

(via Sabine Hossenfelder) Last year, Jonathan Oppenheim’s theory of post-quantum gravity was the only theory that made it into my Best of 2024 summary. Post-quantum gravity is one of the most ...

Until now, creating quantum superpositions of ultra-cold atoms has been a real headache, too slow to be realistic in the ...

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 ...

Famed physicist Stephen Hawking took gravity to its ultimate limits. In doing so, he made a number of significant ...

A new understanding of how an observer can change the disorder, or entropy, of a quantum object could help us probe how ...
