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

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

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...

Pulsars: The Universe's Gift To Physics
2012-02-20 04:22:53

Pulsars, superdense neutron stars, are perhaps the most extraordinary physics laboratories in the Universe. Research on these extreme and exotic objects already has produced two Nobel Prizes. Pulsar researchers now are poised to learn otherwise-unavailable details of nuclear physics, to test General Relativity in conditions of extremely strong gravity, and to directly detect gravitational waves with a "telescope" nearly the size of our Galaxy. Neutron stars are the remnants of massive...

Gravitational Waves Are The 'Sounds Of The Universe'

Einstein wrote about them, and we're still looking for them -- gravitational waves, which are small ripples in the fabric of space-time, that many consider to be the sounds of our universe. Just as sound complements vision in our daily life, gravitational waves will complement our view of the universe taken by standard telescopes. Albert Einstein predicted gravitational waves in 1918. Today, almost 100 years later, advanced gravitational wave detectors are being constructed in the US,...

Squeezed Laser Will Bring Gravitational Waves To The Light Of Day
2011-09-12 06:34:03

  Measuring at the limits of the laws of nature — this is the challenge which researchers repeatedly take up in their search for gravitational waves. The interferometers they use here measure with such sensitivity that a particular quantum phenomenon of light — shot noise — limits the measuring accuracy. With the "squeezed light" method scientists from the Max Planck Society and the Leibniz University Hannover likewise use quantum physics in a countermove in order to...

White dwarfs are the burned-out cores of stars like our Sun. Astronomers have discovered a pair of white dwarfs spiraling into one another at breakneck speeds. Today, these white dwarfs are so near they make a complete orbit in just 13 minutes, but they are gradually slipping closer together. About 900,000 years from now - a blink of an eye in astronomical time - they will merge and possibly explode as a supernova. By watching the stars converge, scientists will test both Einstein's general...

The final piece of Einstein's jigsaw Direct evidence of the existence of gravitational waves is something that has long eluded researchers, however new research has suggested that adding just one of the proposed detectors in Japan, Australia and India will drastically increase the expected rate of detection. In a study published today, Friday, 27 May, in IOP Publishing's journal Classical and Quantum Gravity, Professor Bernard Schutz, of the Albert Einstein Institute, Germany, demonstrated...
