(Phys.org)—While hypothesized dark energy can explain observations of the universe expanding at an accelerating rate, the specific properties of dark energy are still an enigma. Scientists think that dark energy could take ...
Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behaviour of the Universe.

(Phys.org)—Possibly the most well-known consequence of Einstein's theory of special relativity is that nothing can travel faster than the speed of light, c. According to the mass-energy equivalence formula E = mc2, an object ...
UCLA astronomers report the discovery of a remarkable star that orbits the enormous black hole at the center of our Milky Way galaxy in a blistering 11-and-a-half years—the shortest known orbit of any star near this black ...

(Phys.org)—When Einstein described the interaction between two distant objects as "spooky interaction at a distance," he was referring to the quantum phenomenon called steering. Steering can occur in strongly entangled ...
(Phys.org)—Gravitational waves, much like the recently discovered Higgs boson, are notoriously difficult to observe. Scientists first detected these ripples in the fabric of space-time indirectly, using radio signals from ...

(Phys.org) -- Einstein's theory of relativity is remarkable not only because it is so successful in explaining seemingly bizarre observations (like the bending of starlight) or because it has assembled a coherent picture ...

Scientists on Friday said that an experiment which challenged Einstein's theory on the speed of light had been flawed and that sub-atomic particles -- like everything else -- are indeed bound by the universe's speed limit.
