#380887 — Re: Why Gravitational Waves Cannot Exist

An interesting question in StackExchange:

http://physics.stackexchange.com/questions/247376/final-moment-of-the-black-hole-merger-in-the-ligo-publication-means-what 
 "The second paragraph of the LIGO publication talks about the "final moments of the black hole merger" and figure 3 assigns a time scale of less than a second for this to happen. This suggest that black holes merging is a split-second event like two cars crashing into each other. How does this fit with the derivation that an object falling into a black whole will take forever to reach the event horizon --- at least when measured in our frame of reference? Should this not even more be the case for one black hole falling into the other? I would have thought that in particular the "final moments" are stretched out to infinity. Can someone explain the particular meaning of these 0.45 seconds mentioned in the graph?"

Let's see what answers Einsteinians will give.

it is the time delay...

a drift

LIGO conspirators are getting even more enigmatic:

http://phys.org/news/2016-04-ligo-background-noise-due-gravity.html 
 "Prior to the landmark experiments that led to the detection of gravitational waves, researchers believed that there was likely a very nearly constant stream of background gravitational noise moving through the cosmos, generated by black holes and neutron stars merging, but had lacked any physical data that might allow them to estimate how much background noise might exist. With the detection of the gravitational waves that resulted from the merger of two binary black holes, the researchers suddenly found themselves with actual concrete data, which they have now used as a basis for calculating the likely amount of gravitational wave noise constantly bombarding our planet. To make predictions based on data from just one event, the team started with the assumption that the event that was measured was not one that was out of the ordinary... (...) Doing so, the team reports, indicated that there are likely 20 times as many black hole binaries out there as has been estimated, which suggests that there is likely 10 times as much gravitational noise than has been suspected. The team acknowledges that because their results are based on a data from just one event, their conclusions could be wrong, but, if they are right, they note, they should be able to detect them within just the next five years or so as the LIGO and Virgo detectors grow to full strength."

Why should "whopping big signals" (see below) be regarded as noise whose detection will be postponed for five years? If black hole binaries are so frequent, isn't it logical to have, without any delay, multiple detections like the one that allegedly occurred on 14 September 2015?

https://www.theguardian.com/science/2016/feb/09/watch-this-spacetime-gravitational-wave-discovery-expected 
 "People are hugely excited. The rumour is that it's a whopping big signal, in other words, it's unambiguous, and that is fantastic," said Pedro Ferreira, professor of astrophysics at Oxford University, and author of the 2014 book, The Perfect Theory: a century of geniuses and the battle over general relativity."

LIGO in trouble?

http://www.skeptic.com/upcoming-lectures/ 
 Gravitational Waves, Black Holes and the Nature of the Cosmos, Event Date: Sunday, Apr. 10, 2016 at 2 pm, Speaker: Dr. Janna Levin, Tickets: $50 per individual (includes a reserved seat, autographed copy of the guest's book, hors d'oeuvres and wine).

https://twitter.com/michaelshermer/status/719250570280722432?lang=en 
 In case you missed earlier post: Janna Levin livestream today 2pm PST talking about black holes & gravity waves  https://www.youtube.com/watch?v=Hoa8obIWDOc&feature=youtu.be

Yesterday Janna Levin's talk was still advertised on youtube, there was a countdown video, but now there is nothing. Instead, the following article was published an hour ago:

https://aeon.co/essays/how-joe-weber-s-gravity-ripples-turned-out-to-be-all-noise 
 "How Joe Weber's gravity ripples turned out to be all noise" by Janna Levin. "This past February [2016], physicists working on the LIGO experiment reported the discovery of gravitational waves, spacetime ripples predicted by Einstein's general theory of relativity. It was instantly hailed as a sure bet for a Nobel Prize. But 47 years earlier, a now-forgotten pioneer wowed the world with exactly the same claim."
