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 ...

But what if Einstein’s theory of relativity offers a different perspective? What if our inner world, like space-time, is ...

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 ...

Einstein proposed and published his theories of special and general relativity in 1905 and 1915. The concepts are monumental ...

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 ...

In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating black holes as per Einstein’s theory of general relativity. These equations are ...

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...
