Wormholes — yawning gateways that could theoretically connect distant points in space-time — are usually illustrated as gaping gravity wells linked by a narrow tunnel.
A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision.
Gravitational wave detection is going through an even tighter squeeze.
Signals from rare black hole-neutron star pairs could pinpoint rate at which universe is growing, researchers say
Gravitational waves may be forged in the heart of the galaxy, says a new study led by PhD student Joseph Fernandez at Liverpool John Moores University. He sets out the work in a presentation on 3rd April at the European Week of Astronomy and Space Science in Liverpool.
Scientists on the lookout for subtle disturbances in the fabric of space-time have detected the signal from a cataclysmic collision between two black holes that lie some 3 billion light-years away, much farther two previous discoveries.
Researchers have announced the third detection of gravitational waves—ripples in the fabric of space and time.
Three billion years ago, in a third of a second, two black holes crashed into each other and merged into a single entity, converting two solar masses into energy that shook the fabric of spacetime, sending gravitational ripples across the universe that were detected on Earth last January, researchers announced Thursday.
Three’s a party. The LIGO collaboration has made its third observation of gravitational waves emanating from a pair of merging black holes – giving us more insight into how these pairs form and building up our catalogue of them.
A new study pursues a kind of “paleontology” for gravitational waves in an attempt to explain how and why black holes collide and merge.
