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...

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...

"ËœDavid and Goliath' scenario explores extreme mass ratios (Goliath wins) Scientists have simulated, for the first time, the merger of two black holes of vastly different sizes, with one mass 100 times larger than the other. This extreme mass ratio of 100:1 breaks a barrier in the fields of numerical relativity and gravitational wave astronomy. Until now, the problem of simulating the merger of binary black holes with extreme size differences had remained an unexplored region of...

An international group of scientists says it has defined the energy density of gravitational waves created immediately after the birth of the universe. Gravitational waves that still ripple across the universe are believed to result from the Big Bang that created the universe more than 13 billion years ago. Albert Einstein predicted the existence of the waves in 1916, and the first evidence of their existence was reported in 1979. Scientists from the Laser Interferometer Gravitational-Wave...

Scientists hope that a new supercomputer being built by Syracuse University's Department of Physics may help them identify the sound of a celestial black hole. The supercomputer, dubbed SUGAR (SU Gravitational and Relativity Cluster), will soon receive massive amounts of data from the California Institute of Technology (Caltech) that was collected over a two-year period at the Laser Interferometer Gravitational-Wave Observatory (LIGO). LIGO is funded by the National Science Foundation and...
