Besides putting Einstein to the test, the first confirmed observation of gravitational waves will mark the beginning of a new kind of astronomy.

Physicists have described how observations of gravitational waves limit the possible explanations for the formation of black holes outside of our galaxy; either they are spinning more slowly than black holes in our own galaxy or they spin rapidly but are «tumbled around» with spins randomly oriented to their orbit.

The paper, published in Nature, is based on data that came about following landmark observations of gravitational waves by the LIGO gravitational wave detector in 2015 and again in 2017.

Many physicists are hopeful that LIGO will make the first direct observation of gravitational waves in the next few years.

A new observation of gravitational waves, announced by scientists with the Advanced Laser Interferometer Gravitational - Wave Observatory, LIGO, follows their first detection, reported earlier this year (SN: 3/5/16, p. 6).

LIGO's observation of gravitational waves directly confirmed a 100 - year - old prediction of Einstein's general theory of relativity — that rapidly accelerating massive objects stretch and squeeze spacetime, producing ripples that travel outward from the source (SN: 3/5/16, p. 22).

The event, reported last October, marked the fifth observation of gravitational waves — ripples in the very fabric of spacetime, caused by huge cosmic cataclysms.

Indeed, the very first indirect observations of gravitational waves were made with pulsars: it was found that their rotational energy was decreasing (they rotated more slowly over time), at exactly the rate that we would expect if they were shedding that energy by giving off gravitational waves!

The Laser Interferometer Gravitational - wave Observatory (LIGO) broke the news almost one year ago about the first - ever direct observation of gravitational waves.

That movement signified the first observation of gravitational waves.

Editor's Note (10/3/17): This year's Nobel Prize in Physics was awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne «for decisive contributions to the LIGO detector and the observation of gravitational waves.»

The existence of black holes tens of times more massive than our Sun was confirmed recently by the observation of gravitational waves, produced by the merger of pairs of massive black holes, with the LIGO interferometer.

Though researchers often wait decades for Nobel recognition, the observation of gravitational waves was so monumental that the scientists were honored less than two years after the discovery's announcement.
