This is the first spacetime to be written down in which a warp-drive is not required to have exotic negative energy. That one ...

In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

Mind = blown.

Although quantum mechanics and general relatively help explain the universe—at both small and cosmic scales—the two theories are fundamentally incompatible with each other. This has spawn theories ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

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 ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...

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 ...
