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 ...

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 ...

Here’s how it works. General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the ...

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 ...

Gravity is the force that attracts two objects with mass towards each other. It is one of the most familiar forces in our daily lives, responsible for keeping us on the ground and the planets in orbit ...

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum gravity" could arise from entropy, possibly solving puzzles put forth ...

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 physicists ...

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

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 ...
