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

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

Einstein's theory of general relativity has passed its toughest test with flying colors, a new study reports. General relativity, which Einstein proposed in 1916, holds that gravity is a consequence ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

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

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

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 ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...
