'Dark Matter' Forms Ghost Universe That Mirrors Our Own, New Theory Shows
November 10, 2003 — The "dark matter" that comprises a still-undetected one-quarter of the universe is not a uniform cosmic fog, says a University of California, Berkeley, astrophysicist, but instead forms dense ... > full story -
Einstein's Gravitational Waves May Set Speed Limit For Pulsar Spin
July 7, 2003 — Gravitational radiation, ripples in the fabric of space predicted by Albert Einstein, may serve as a cosmic traffic enforcer, protecting reckless pulsars from spinning too fast and blowing apart, ... > full story -
Berkeley Lab Physicist Challenges Speed Of Gravity Claim
June 19, 2003 — Albert Einstein may have been right that gravity travels at the same speed as light but, contrary to a claim made earlier this year, the theory has not yet been proven. A scientist at Lawrence ... > full story -
NASA Researchers Put New Spin On Einstein's Relativity Theory
April 10, 2003 — Researchers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have discovered that entanglement is relative, depending on how fast an observer moves with respect to the particles, and that ... > full story -
NIST Helping Prepare An "Out Of This World" Atomic Clock
November 12, 2002 — Setting the world's clocks from a timepiece far above the Earth someday may be the norm if the National Institute of Standards and Technology (NIST)-led program to put an atomic clock aboard the ... > full story -
Gravity Waves Analysis Opens "Completely New Sense"
October 29, 2002 — Sometime within the next two years, researchers will detect the first signals of gravity waves -- those weak blips from the far edges of the universe passing through our bodies every second. ... > full story -
International Team Of Scientists Attempts To Measure Speed Of Gravity
September 12, 2002 — Ever since Albert Einstein proposed the general theory of relativity in 1916, physicists worldwide have tested the theory's underlying principles. While some principles - such as the speed of ... > full story -
New Insights Into Open String Theory
June 27, 2002 — Theoretical physicist Lennaert Huiszoon has described a new family of strings in research conducted at the National Institute for Nuclear Physics and High Energy Physics. He investigated so-called ... > full story -
Was Einstein Wrong? Space Station Research May Find Out
May 30, 2002 — Ultra-precise clocks on the International Space Station and other space missions may determine whether Albert Einstein's Special Theory of Relativity is correct and could dramatically change our ... > full story -
Los Alamos Researcher Says "Black Holes" Aren't Holes At All
April 23, 2002 — Researchers from the U.S. Department of Energy's Los Alamos National Laboratory and the University of South Carolina have provided a hypothesis that "black holes" in space are not holes ... > full story
