The model questions the popular inflation theory, which most experts believe was facilitated after the universe's birth. The ...

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

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 ...

Einstein was a great thinker who made plenty of mistakes—errors that sometimes led to more meaningful discoveries in physics, ...

Saint Louis University — Madrid mathematics Professor Robert Monjo, Ph.D., recently led a study on the shape of Einstein's concept of spacetime now published in "General Relativity and Gravitation." ...

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 ...

Astronomers have made a groundbreaking discovery of a ‘dark object’ concealed within a warped ‘Einstein ring’ located 10 ...
