The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not dissimilar to what happens when you put a bowling ball on a trampoline. This ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

By constructing these so-called Einstein-Rosen caterpillar wormholes, researchers offer a tangible way to imagine what the inside of a typical black hole might look like. Rather than being smooth or ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

Jury’s still out on the “frame-dragging” business. That’s according to this news report from an academic conference yesterday: After half a century, seven cancellations and $700 million, a mission to ...

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 Google Deep Mind researcher and physics expert, Adam Brown, discusses what an AI Einstein would be like. Einstein coming up with General Relativity required coming up with new notation. Einstein’s ...
