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

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 ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

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 ...
