Physicists Presently Detected Gravitational Waves for the 2nd Time Ever

It was one of the major moments in recent reminiscence when an international squad of physicists announced that they’d made the 1st direct observations of gravitational waves since Einstein first future them a century ago. Now, presently four months later, an Australian team has announced the next such achievement - they’ve directly detect gravitational waves caused by the crash of two black holes that are up to 14 times the size of our Sun.
"This has paved the age of gravitational wave astronomy," said one of the team, Susan Scott, an astrophysicist from the Australian National College (ANU) in Canberra. "This shows data is leaving to flow, that will enable us to map a lot extra of the Universe than we’ve seen before."
Scott and her team have been analysing data collected by the 2 Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors in the US - the same detectors that picked up that significant gravitational wave signal on 14 September 2015, before it was analysed and announce in February.
On 26 December 2015, Australian researchers wedged a glimpse of two black holes orbiting every other 27 times in their last second previous to colliding. The explosion signal that resulted was 10 times longer than that of the 1st  gravitational wave, and now the team has finally had a possibility to analyse it.
They’ve figured out that this collision actually happen 1.4 billion years ago, in a galaxy so distant, the resulting shockwaves have only presently reached us.
Predict by Einstein back in 1916, gravitational waves are ripples in the curvature of spacetime that emanate from the most volatile and violent events in the Universe, such as a star exploding or a black hole merger.
These ripple spread out through space like the ripples in a pond after a stone’s been toss in, and - in the two cases we’ve been able to notice them - by the time those ripples get to us on Earth, they’re tiny. We’re talking about a billionth of the diameter of an atom.Einstein himself predict that humans would never be able to detect them because of how minuscule their signal would be. Until these LIGO comments, scientists have been making sense of the Universe based on electromagnetic observations that our instrument can detect, such as visible light emissions, radio waves, and X-rays.
Being able to dependably detect gravitational waves too means we have an completely new way to 'see' and measure the substance and events in space around us.
"I'd forever imagined there would be electromagnetic counterpart in our first discoveries, but instead we found these imperceptible collisions of black holes only through the gravitational waves they emitted, with no counterpart at all," says one of the team, Rob Ward. "Gravitational wave astronomy is departing to revolutionize our understanding of the Universe."
