For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible ...

A recent study published in Nuclear Physics B examines how hidden dimensions might influence the physical reality that we ...

Astronomers have finally watched a black hole twist spacetime in real time, catching the fabric of the universe itself ...

Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...

A supermassive black hole was caught twisting spacetime, offering the clearest real-world evidence yet for Einstein’s ...

A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden ...

Physicists from the Eötvös Loránd University (ELTE) have been conducting research on the matter constituting the atomic nucleus, utilizing the world’s three most powerful particle accelerators. Their ...

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 ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
