Photons 'Entangle' Way Faster Than Light Speed

Physicists try to measure 'quantum teleportation'

(Newser) - Quantum action occurs very, very quickly—at least 10,000 times the speed of light. That's the finding of a team of Chinese physicists who tried to measure the interaction between entangled photons, LiveScience reports. In case you don't know: "Connected" photons can be separated but still... More »

Einstein Safe: Neutrinos Do Not Break Light Speed

New experiment shows particles at identical speed with light

(Newser) - Einstein's theory apparently remains untouchable, and flabbergasted theoretical physicists can cease hyperventilating: Neutrinos do not exceed the speed of light, but they do appear to travel at the same speed as light, according to the results of a recent experiment. The new data confirm Einstein's foundational ideas and... More »

Faster-Than-Light Findings All Wrong: New Study

Scientists refute labmates' shocking results

(Newser) - The scientists who said they recorded particles traveling faster than light in September —and then confirmed their own findings last week —have it wrong, international scientists in Italy say. The ICARUS project, based in the same laboratory as the OPERA experiment, argued that if the particles had traveled... More »

2nd Test Finds Faster-Than-Light Particles

Result backs up much-hyped, and much criticized, earlier experiment

(Newser) - The international physics team OPERA (Oscillation Project with Emulsion Tracking Apparatus) has managed to recreate the result that shocked the physics world , again detecting a batch of subatomic particles moving faster than the speed of light, the Washington Post reports. The "positive outcome of the test makes us more... More »

Scientists: Time Travel Impossible

Researchers prove nothing can violate the 'traffic laws' of the universe

(Newser) - Wait, so Bill And Ted's Bogus Journey is suddenly implausible? A group of Hong Kong University of Science and Technology physicists say they've proven that time travel is physically impossible, reports Discovery News . They demonstrated that a single photon obeys Einstein's theory that nothing can travel faster... More »

Experts: Warp Drive Is Possible

Physicists theorize warping space could allow faster-than-light travel

(Newser) - Two physicists believe the fictional "warp drive" of Star Trek fame could someday become a reality, the Daily Telegraph reports. The scientists theorize that a mysterious cosmic force called dark energy could be harnessed to warp space around a vessel, allowing a spacecraft to travel faster than light—"... More »

Trapping the Colors of the Fiber Rainbow

Researchers say halting and storing light would revolutionize computing

(Newser) - One of the immutable laws of physics is that nothing can travel faster than the speed of light, about 186,000 miles per second. But The Economist reports new research shows it may be possible to slow down light to a virtual halt, and even store it. If that could... More »

Scientists Breach Einstein's Theory

Photons traveled faster than light, say Germans

(Newser) - Two German physicists claim to have sent microwave photons zooming past the speed of light , a feat Albert Einstein said would require an infinite—and impossible—amount of energy, reports the Daily Telegraph. "For the time being, this is the only violation of special relativity that I know of,... More »
