Astronomers have reported a bumper crop of new gravitational wave detections. The 35 new signals, comprising the third Gravitational-Wave Transient Catalog (GWTC-3), help scientists probe the depths of the cosmos in more detail.Continue ReadingCategory… Continue reading Spacetime shimmers in bumper crop of new gravitational wave detections
There are many mysteries surrounding black holes, and now a team of astronomers has proposed a novel solution to one of them – why are so many observed black holes more massive than expected? A new model suggests that their growth may be “cosmologicall… Continue reading New model suggests black holes gain mass as the universe expands
A new type of gravitational wave detector running in Western Australia has recorded two rare events that might be signals of dark matter or primordial black holes. These high-frequency gravitational waves are beyond the range of most detectors and have… Continue reading Never-before-detected gravitational waves hint at dark matter
It’s tricky business detecting gravitational waves – these ripples in the very fabric of spacetime are often drowned out by background vibrations from earthquakes, traffic and other human activity. Now a pair of astrophysicists has proposed a new locat… Continue reading Putting a gravitational wave detector on the Moon could find new physics
Detecting gravitational waves from collisions between two black holes or two neutron stars is becoming almost mundane, but now astronomers have detected the final piece of the trifecta – a black hole swallowing a neutron star. Two separate events rolle… Continue reading Gravitational wave trifecta completed as black holes eat neutron stars
With elusive dark matter continuing to evade detection, scientists are having to search in stranger and stranger places. In a new study, physicists at MIT have studied the spins of black holes for signs of drag from dark matter slowing them down.Contin… Continue reading Physicists hunt for dark matter dragging on black holes
Gravity is one of the more obvious forces in the universe, generally regarded as easily noticeable by the way apples fall from trees. However, the underlying mechanisms behind gravity are …read more Continue reading How The LIGO Observatory Detects Gravitational Waves
Just a few months ago, scientists reported the detection of very low-frequency gravitational waves. Now a pair of German astrophysicists has investigated two intriguing possible sources – the universe cooling down after the Big Bang, and a field of par… Continue reading Dark matter or cooling “primordial soup” could create gravitational waves
Last year scientists detected gravitational waves from what appeared to be the most massive black hole collision ever recorded. But now an international team of astrophysicists has proposed an exotic alternative – the data may actually favor a collisio… Continue reading Invisible “dark matter” stars may explain puzzling gravitational waves
The gravitational waves we’ve detected so far have been like tsunamis in the spacetime sea, but it’s believed that gentle ripples should also pervade the universe. Now, a 13-year survey of light from pulsars scattered across the galaxy may have reveale… Continue reading Astronomers may have detected background ripples in spacetime itself
