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 ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

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 ...

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

Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely ...

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the ...

The study, titled "Gravity from Entropy," introduces a novel approach that derives gravity from quantum relative entropy, bridging the gap between two of the most fundamental yet seemingly ...

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 ...

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 ...
