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 ...

Some habitable worlds orbiting dead stars could be kept alive for aeons thanks to a quirk of Einstein’s theory of gravity ...

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 ...

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

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 ...

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 ...

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 ...

On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. Einstein's theory suggested that gravity could bend light by curving the fabric of spacetime. To ...

As the Moon’s shadow creeps across the Sun on April 8, physicist Aroh Barjatya will launch a trio of 60-foot-tall rockets into the highest layer of Earth’s atmosphere. The short, sudden darkness of a ...

Seven Days is 30, and we need your help to celebrate. With your donation, we’ll stay on track, delivering rigorous reporting on Vermont news and culture. In 1919, astronomer Arthur Eddington used the ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...
