Albert Einstein changed science forever with special and general relativity, redefining space, time, and gravity. Yet after ...

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 ...

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the ...

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 ...

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 ...

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 ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

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 ...

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 ...

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 massive galaxy has created a rare distortion in the path of light that has traveled billions of years to reach us from a more distant galaxy. It's called an Einstein cross – when the curvature of ...
