Black hole collision may have exploded with light
... allowed the ZTF scientists to look for light signals from the location where the gravitational wave signal originated. These gravitational wave detectors have also spotted mergers between dense cosmic objects called neutron stars, and astronomers...

Arecibo - an astounding legacy
... observed in the periastron of the binary system – the point of closest approach - led to the first indirect evidence of gravitational waves. The first radar ranging of an Earth-crossing asteroid, 1862 Apollo, was done in 1980 and, a year later...

Short gamma-ray burst is from a binary neutron star coalescing into a black hole say researchers
... distance to the two events, but it will also, amongst other things, help pinpoint the location of the gravitational wave event. Now, an international team of researchers have submitted a research paper that states that this idea is in fact...

Three massive black holes caught in the act of merging
... the first observation of a binary black hole merger in February 2016, it was not just gravitational waves that were caught rippling through Earth; a wave of feverish excitement reserved for only the most spectacular of discoveries also surged around...

Are our ideas of Dark Matter wrong?
... was extremely hot – the hottest it could have been. To test their theory the team suggest several gravitational waves from the very early moments of the Universe would have been created and that these might...

Does the speed of light change with time?
... are popular and many different versions of the theory have been put forward, including a publicised announcement of gravitational waves from ‘inflation’ in 2014, which turned out to be due to cosmic dust. But the drawback with inflation is that...
