For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the ...

Albert Einstein's theory of general relativity is based on the idea that massive objects cause a distortion in space-time, which is felt as gravity ...

A festinating new theory shifts focus from space to time, arguing the clock-ticking we take for granted is richer and weirder ...

A researcher throws cold water on a recent effort that purported to eliminate black holes' greatest and most enduring mystery ...

A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable.. This is the conclusion of ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is ...

New mathematical work provides a way to identify when information has been changed by manipulating space-time – and it may ...

In general relativity matter tells space-time how to curve, and curved space-time tells matter how to move. (Getty Images: Levente_Naghi)This was a departure from Isaac Newton's view of gravity ...

Einstein’s theory of general relativity sees gravity as the curvature or warping of spacetime by an object, with more massive objects having a greater effect on the spacetime surrounding them.
