There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

The most surprising element is that a MOND-influenced theory of gravity—also co-authored by Milgrom—explains this unexpected ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The study of black holes within the framework of general relativity continues to advance our understanding of gravitation under extreme conditions. Black holes, with their intricate interplay of mass, ...

Michelson's interference experiment / by H.A. Lorentz -- Electromagnetic phenomena in a system moving with any velocity less than that of light / by H.A. Lorentz -- On the electrodynamics of moving ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...

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 ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...
