Alan Weinstein - “Recent results on Gravitational Waves from LIGO and Virgo”

[@KevinECahill]

The video should have shown a close-up of the screen instead of a wide-angle view of the auditorium. But Alan Weinstein gave a great talk.

Very informative,thanks. Is it possible to get a copy of the slides? They're hard to read on the video.

"Trust Einstein but verify", or trust nobody, always verify.

each time he clicks his laser i get sound -.-

Does Einstein's general relativity predict that gravitational waves travel at the speed of light? Does it predict how the Shapiro delay for gravitational waves compares with the Shapiro delay for light? The answer to both questions is 'no'. According to Arthur Eddington, Einstein's general relativity says nothing about the speed of gravitational waves, let alone their Shapiro time-delay: Arthur Eddington: "The statement that in the relativity theory gravitational waves are propagated with the speed of light has, I believe, been based entirely upon the foregoing investigation; but it will be seen that it is only true in a very conventional sense. If coordinates are chosen so as to satisfy a certain condition which has no very clear geometrical importance, the speed is that of light; if the coordinates are slightly different the speed is altogether different from that of light. The result stands or falls by the choice of coordinates and, so far as can be judged, the coordinates here used were purposely introduced in order to obtain the simplification which results from representing the propagation as occurring with the speed of light. The argument thus follows a vicious circle." The Mathematical Theory of Relativity, pp. 130-131 www.amazon.com/Mathematical-Theory-Relativity-S-Eddington/dp/0521091659 So what is the a priori probability that the gravitational waves (if they exist) arrive simultaneously with the optical signal? Answer: Zero. That is, if, in the neutron star case, LIGO's fabrication involved different times of arrival, that would at least have sounded realistic. The claim that the gravitational waves and the optical signal arrived at exactly the same time, which implies that they not only travel at the same speed but also experience the same Shapiro delay, unequivocally proves that LIGO conspirators just faked the gravitational wave signals. The noise correlation found in LIGO data leads to the same conclusion - LIGO conspirators had no idea what they were "measuring" (faking) and produced signal correlation but also noise correlation that they are unable to explain: Sabine Hossenfelder: "Was It All Just Noise? Independent Analysis Casts Doubt On LIGO's Detections. A team of five researchers - James Creswell, Sebastian von Hausegger, Andrew D. Jackson, Hao Liu, and Pavel Naselsky - from the Niels Bohr Institute in Copenhagen, presented their own analysis of the openly available LIGO data. And, unlike the LIGO collaboration itself, they come to a disturbing conclusion: that these gravitational waves might not be signals at all, but rather patterns in the noise that have hoodwinked even the best scientists working on this puzzle. [...] A few weeks ago, Andrew Jackson presented his results in Munich. A member of the local physics faculty (who'd rather not be named) finds the results "quite disturbing" and hopes that the collaboration will take the criticism of the Danes to heart. "Until LIGO will provide clear scientific(!) explanation why these findings are wrong, I would say the result of the paper to some extent invalidates the reliability of the LIGO discovery." [...] This is a Nobel-worthy discovery and much is at stake. Even the smallest doubt that something is at odds should be erased." www.forbes.com/sites/startswithabang/2017/06/16/was-it-all-just-noise-independent-analysis-casts-doubt-on-ligos-detections/
