The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

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 doomed star spiraling into a supermassive black hole has given physicists one of their clearest looks yet at how gravity ...
