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 ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. Image of the galaxy NGC 6505: the Einstein ring created by this gravitational lens can be seen in ...

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

University of Wyoming President Ed Seidel will deliver the Department of Physics and Astronomy’s fall 2025 Rebka-Hafele-Einstein Distinguished Lecture Friday, Nov. 7.

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 ...

Interstellar object 3I/ATLAS has seemingly confirmed Einstein's general relativity by exhibiting gravitational lensing as it neared the Sun. However, the observed light bending exceeded predictions by ...

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 ...

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 ...
