BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...

Watch as one of the most famous theories in physics is broken down in a way that reveals what’s really happening. Special ...

The loudest collision ever recorded between two black holes has allowed scientists to test Einstein’s theory of general relativity in unprecedented detail, showing that the physicist’s predictions ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. These distortions travel far out into the universe, but by the time they reach Earth, they have ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Two cutting-edge atomic clocks — the most accurate ever ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...
