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 ...

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

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

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

The established classical concept of gravity is Einstein’s general theory of relativity. This spectacularly successful theory has correctly predicted phenomena from the bending of light and the ...

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 ...

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

Furthermore, because gravitational interactions are weak, more precision is needed to study true quantum gravity effects beyond general relativity, which is a classical theory. "A quantum theory ...

And thanks to Einstein's theory of gravity, we know enough to map the path of orbiting planets and colliding galaxies. Loading... His theory of general relativity has been unsurpassable since it ...
