Confirmed by an eclipse, Einstein's theory of gravity revealed a spectacular tool: gravitational lensing. This video explains ...

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales. When you purchase ...

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

Learn how Albert Einstein’s theory reveals that time on Mars runs faster than on Earth — and why that tiny shift matters for ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

For more than 100 years, Albert Einstein’s general theory of relativity has been our best description of how the force of gravity acts throughout the Universe. General relativity is not only very ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

One hundred years after Albert Einstein proposed his theory of general relativity, a theoretical physicist, Erik Verlinde from the University of Amsterdam, proposes a revision, suggesting that gravity ...

An orbital oopsie has led to new proof of Albert Einstein’s physics prowess. In 2014, two satellites intended for Europe’s Galileo network, the equivalent of the United States’ GPS network, were ...

Of course, in science, you’re only as good as your last successful calculation and that means that scientists are constantly working out new ways to test Einstein’s ideas. Astronomers have recently ...
