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

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 ...

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

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

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, ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

GENEVA - A pillar of physics - that nothing can go faster than the speed of light - appears to be smashed by an oddball subatomic particle that has apparently made a giant end run around Albert ...

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...
