Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

Even if it turns out that time loops never take shape, studying them provides key insights into the deepest rules of reality.

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

“The chief attraction of the theory lies in its logical completeness,” wrote Albert Einstein after publishing his general theory of relativity in 1915. “If a single one of the conclusions drawn from ...

The supermassive black hole at the center of the Milky Way is the most extreme astrophysical object located within a million light-years of Earth. With an estimated four million solar masses, it's the ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you were a physicist in the early 20th century, there would have ...
