[ Watch the Video: Atomic Interferometer To Predict Gravitational Waves ] April Flowers for redOrbit.com - Your Universe Online NASA is pursuing a pioneering technology capable of atomic-level precision to detect gravitational waves or ripples in space-time caused by cataclysmic events, including the Big Bang itself. Researchers at NASA's Goddard Space Flight Center, AOSense, Inc and Stanford University have been awarded funding under NASA's Innovative Advanced Concepts (NIAC)...

Scientists measure interference between matter waves separated by 0.1 mm While airplane and rocket experiments have proved that gravity makes clocks tick more slowly "“ a central prediction of Albert Einstein's general theory of relativity "“ a new experiment in an atom interferometer measures this slowdown 10,000 times more accurately than before, and finds it to be exactly what Einstein predicted. The result shows once again how well Einstein's theory describes the real world,...

PTB researchers want to construct the "atomic clock of the future" much more simply and more compactly than the previous elaborate laboratory set-ups You imagine a clock to be different - yet the optical table with its many complicated set-ups really is one. Optical clocks like the strontium clock in the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig could be the atomic clocks of the future; some of them though are already ten times more precise and stable than the best primary...
