Found! Gravitational Waves, or a Wrinkle in Spacetime
Found! Gravitational Waves, or a Wrinkle in SpacetimeRipples produced by enormous cosmic events could open a new era in astronomy. After nearly a century, the hunt for an elusive cosmic quarry is over. With the help of lasers and mirrors, scientists have directly observed gravitational waves, or wrinkles in the fabric of spacetime itself. Two colliding black holes, one with 36 times the mass of th
Gravitational waves: Einstein was right - and this announcement is the scientific highlight of the decade
Physicists and astronomers are agog. On Thursday, experimenters will report the first detection of a phenomenon that has been long predicted:bursts of gravitational waves generated by cosmic collisions of black holes. Sadly it is not unknown for hyped-up scientific claims to be mistaken or exaggerated - claims of particles going faster than light, gravitational waves from the big bang, and so fort
Observation of Gravitational Waves from a Binary Black Hole Merger
On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0×10−21. It matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and
Gravitational Waves Detected, Confirming Einstein’s Theory (Published 2016)
About a hundred years ago, Einstein predicted the existence of gravitational waves, but until now, they were undetectable.CreditCredit...Artist's rendering/Simulating eXtreme Spacetimes A team of scientists announced on Thursday that they had heard and recorded the sound of two black holes colliding a billion light-years away, a fleeting chirp that fulfilled the last prediction of Einstein’s gener
The First Detection Of Gravitational Waves Validates Einstein In A Whole New Way!
This morning, the principal investigator of the Laser Interferometer Gravitational-wave Observatory (LIGO), David Reitze, made the big announcement: "Ladies and gentlemen, we have detected gravitational waves." Some 1.3 billion light years away, two black holes of approximately 30 times the mass of the Sun each merged together, spiraling into one another and becoming one even more massive black ho
How the First Gravitational Waves Were Found
A hundred years ago, Albert Einstein predicted the existence of moving ripples in space and time.Illustration by Aleks Sennwald Note: On October 3, 2017, the Royal Swedish Academy of Sciences announced that the Nobel Prize in Physics would be awarded to Rainer Weiss, Kip Thorne, and Barry Barish, three pioneers in the study of gravitational waves. Just over a billion years ago, many millions of ga
Einstein's gravitational waves 'seen' from black holes
Pallab Ghosh explains the sound of the gravitational wave and a computer visualisation Scientists are claiming a stunning discovery in their quest to fully understand gravity. They have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth. The international team says the first detection of these gravitational waves will usher i
