A new theory suggests gravity could possibly be the result of entropy—which would mean everything in the universe would fall ...

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

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, ...

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 ...

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

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 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, ...

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 ...
