The theory of general relativity upended the world of physics and even its author resisted accepting a bizarre phenomenon the ...

Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...

Solar eclipses are a rare and brief opportunity for scientists to gather data on everything from the physics of the sun to ...

What do Albert Einstein, the Global Positioning System (GPS), and a pair of stars 200,000 trillion miles from Earth have in common? While scientists have found incontrovertible evidence of ...

Everyone knows Albert Einstein was a genius, but can you explain what he’s famous for? Arguably his foremost theory, his general theory of relativity, turns 100 years old this week. It was actually ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...

More than a century has passed since Albert Einstein gave us general relativity, and scientists are still testing the mind-bending theory. In the latest test, an international team of astronomers used ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

In the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, researchers report that Einstein's theory of general relativity holds up, at least for ...
