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

Mind = blown.

General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...

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 ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

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

A collapsing warp bubble like the one seen in Star Trek would set space ringing with gravitational waves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime.

Physicists long believed time was a basic feature of the universe. But it may just emerge from cosmic information.
