Atom Optics To Predict Gravitational Waves
2012-10-19 08:33:13

[ 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)...

Star Discovery Tests Einstein
2012-10-04 20:58:20

Lee Rannals for redOrbit.com — Your Universe Online Astronomers, using the Keck Observatory, have found the star they need to test Einstein's theory about the fabric of space-time. UCLA astronomers said they have discovered a star that orbits the enormous black hole at the center of our Milky Way that will help discover whether Albert Einstein was right in his fundamental prediction of how black holes warp space and time. The star, S0-102, orbits the black hole every...

Merging Black Holes Could Reveal Their Flashy Secrets
2012-09-29 08:09:37

[ Watch the Video: Black Holes Crash, Merge in New Simulations ] April Flowers for redOrbit.com - Your Universe Online Einstein predicted gravitational waves almost 100 years ago. According to his theory, whenever massive objects interact, they produce distortions in the very fabric of space and time that ripple outward across the universe at the speed of light. Modern astronomers have found indirect evidence of these waves, but so far they have eluded direct detection. Greater...

black hole
2012-09-18 05:29:06

April Flowers for redOrbit.com - Your Universe Online Recent research from the University of Cardiff has found that the dying tones of black holes reveal the cosmic crash that caused them to form. Black holes are regions of space where gravity is so strong that not even light can escape. Usually, they are the evolutionary ending of stars that were 10 to 15 times larger than our sun. After these stars undergo a supernova event, sometimes the remnant will collapse in on itself, creating a...

Two White Dwarf Stars Emit Gravitational Waves
2012-08-29 07:35:26

April Flowers for redOrbit.com - Your Universe Online Researchers led by the University of Texas at Austin and the Harvard-Smithsonian Center for Astrophysics have confirmed the emission of gravitational waves from the second strongest known source in our galaxy by studying the shrinking orbital period of a unique pair of burned-out stars. The results, which will be published soon in The Astrophysical Journal Letters, tested Einstein's theory of general relativity in a new way. Last...

Looking Into The Heart Of A Supernova
2012-07-12 21:01:00

Caltech simulation points out how to detect a rapidly spinning stellar core Each century, about two massive stars in our own galaxy explode, producing magnificent supernovae. These stellar explosions send fundamental, uncharged particles called neutrinos streaming our way and generate ripples called gravitational waves in the fabric of space-time. Scientists are waiting for the neutrinos and gravitational waves from about 1000 supernovae that have already exploded at distant locations in...

New Data Supports Einstein's Explanation For Dark Matter
2012-04-03 08:07:50

New information obtained by scientists using a 10-meter telescope located in Antarctica has strengthened the most widely accepted explanation for the mysterious force that is behind the increasingly rapid expansion of the universe, according to a pair of press releases published this week. According to a statement from the National Science Foundation (NSF), the most recent South Pole Telescope (SPT) data "strongly" supports Albert Einstein's cosmological constant, said to be the leading...

String Theory -- A string theory is a physical model whose fundamental building blocks are extended objects (strings, membranes and higher-dimensional objects) rather than points. String theories are able to avoid problems, such as infinite energy density, associated with the presence of mathematical points in a physical theory. The term 'string theory' properly refers to both the 26 dimensional bosonic string theories and to the 10 dimensional superstring theories discovered by...

Spacetime
2004-10-19 04:45:42

Spacetime -- In special relativity and general relativity, time and three-dimensional space are treated together as a single four-dimensional manifold called spacetime (alternatively, space-time; see below). A point in spacetime may be referred to as an event. Each event has four coordinates (t, x, y, z). Just as the x, y, z coordinates of a point depend on the axes one is using, so distances and time intervals, invariant in Newtonian physics, may depend on the reference frame of an...
