Fastest eclipsing binary, a valuable target for gravitational wave studies
Jul 26, 2019 (SPX)
Clocking in with an orbital period of only 6.91 minutes, the rapidly orbiting stars are expected to be one of the strongest sources of gravitational waves detec...
Chameleon Theory Could Change How We Think About Gravity
Jul 09, 2019 (SPX)
Physicists at Durham University, UK, simulated the cosmos using an alternative model for gravity - f(R)-gravity, a so called Chameleon Theory. The resulting ima...
Artificial gravity breaks free from science fiction
Jul 05, 2019 (SPX)
Now, a team from CU Boulder is working to make those out-there technologies a reality. The researchers, led by aerospace engineer Torin Clark, can't mimic those...
Researchers find quantum gravity has no symmetry
Jun 21, 2019 (SPX)
"Many physicists believe that there must a beautiful set of laws in Nature and that one way to quantify the beauty is by symmetry. Some of the symmetries may be...
Development of a displacement sensor to measure gravity of smallest source mass ever
May 23, 2019 (SPX)
Professor Nobuyuki Matsumoto has led a team of researchers to develop a gravity sensor based on monitoring the displacement of a suspended mirror, which allows ...
Gravitational waves leave a detectable mark, physicists say
May 10, 2019 (SPX)
And while the billion-dollar Laser Interferometer Gravitational-Wave Observatory (LIGO) detector watches 24/7 for gravitational waves to pass through the Earth,...
UCLA students touch space with a microgravity experiment
May 10, 2019 (SPX)
At 6:32 a.m. on May 2, their experimental pump designed for use in zero-gravity environments, named "Blue Dawn ," completed its flight into a low-Earth orbit an...
LIGO and Virgo Detect Neutron Star Smash-Ups
May 03, 2019 (SPX)
"The universe is keeping us on our toes," says Patrick Brady, spokesperson for the LIGO Scientific Collaboration and a professor of physics at the University of...
Scientists Find More Evidence the Universe Is a Violent Place
May 03, 2019 (SPX)
"These two new triggers are further evidence that our universe regularly rings with the aftershocks of colossal astronomical events," said Professor Sheila Rowa...
What Earth's gravity reveals about climate change
Apr 23, 2019 (SPX)
This so-called time-resolved satellite gravimetry makes it possible, among other things, to monitor the terrestrial water cycle, the mass balance of ice sheets ...
Ten years before the detection of gravitational waves
Apr 08, 2019 (SPX)
"For the first 15 or 16 years of my career I was speaking to astronomers, and I always had the impression that they were politely interested in what I had to sa...
Upgraded Detectors to Resume Hunt for Gravitational Waves
Mar 27, 2019 (SPX)
Over the last year upgrades have been put in place to the mirrors, lasers and other components of the US based LIGO detectors that that will increase the detect...
New compute cluster to find and interpret gravitational waves
Mar 24, 2019 (SPX)
"Our new cluster, Hypatia, is dedicated to data analysis as well as to astrophysical, cosmological and fundamental physics studies of gravitational waves," says...
Taking gravity from strength to strength
Mar 21, 2019 (ESA)
Because of factors such as the planet's rotation, the position of mountains and ocean trenches and different densities in materials in Earth's interior, the for...
Resolving the jet or cocoon riddle of a gravitational wave event
Feb 22, 2019 (SPX)
In August 2017, two neutron stars were observed colliding, producing gravitational waves that were detected by the American LIGO and European Virgo detectors. N...
