Detection of gravitational waves, whose existence one hundred years ago, predicted by albert Einstein in February of 2016 was no accident — scientists have documented distortions in space-time, the second time, reports Reuters.
The researchers said that discovered around the Earth the gravitational waves were caused by the collision of two black holes moving in a spiral towards each other and collided in one about 1.4 billion years ago.
Gravitational waves observed double observatories in the United States late in the evening of 25 December 2015. The sensors were located in Livingston, Louisiana and Hanford, Washington.
For the first time gravitational waves was discovered in September of last year, but announced they only had 11 Feb 2016. This event became a scientific sensation, which confirmed the conjecture Einstein made nearly a century ago. As stated at the press-conference of the international group of physicists that made the discovery, it will allow a better understanding of the mysterious objects like black holes and neutron stars, as well as to get an idea about the early period of the existence of the Universe.
The first and second detected gravitational waves, were caused by the collision of two black holes. In the first case, they were a mass about 30 times greater than the Sun and came across 1.3 billion light years from Earth. The second detected wave is much smaller than the first, says Reuters.
As stated by astrophysicist of the University of Pennsylvania Chad Hanna, “now that we are able to detect gravitational waves, they will become a phenomenal source of new information about our galaxy and an entirely new channel for discoveries about the Universe.”
