The most detailed map of the universe ever created using gravitational waves could reveal hidden black holes, merging ...

Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

For centuries, gravity has been one of the most captivating and puzzling forces in the universe. Thanks to the groundbreaking ...

Why Do Black Holes Form? Black holes form when a huge amount of matter is squeezed into a very small space. Cram enough ...

A model where both matter and space-time obey quantum mechanics is often considered the fundamental description of nature.

Extreme stars may possess mountains similar to those found on moons in our solar system, potentially creating detectable ...

The theory is a series of equations defined by Einstein. These equations combine space and time to create space-time. Gravity is explained by these equations, which are consistent with what we see ...

When Albert Einstein introduced his theory of general relativity in 1915, it changed the way we viewed the universe. His ...

The search for quantum gravity has gone on for 100 years, but it is not the only unification challenge in physics. Many of us ...

"We can perform transformations of motion so that gravity and electromagnetism can be deduced from the same equation of spacetime." Monjo’s theory helps unify scientific concepts of Newtonian ...
