"On September 16, 2010, a false signal - a so-called "blind injection" - was fed into both the Ligo and Virgo systems as part of an exercise to "test ... detection capabilities". At the time, the vast majority of the hundreds of scientists working on the equipment had no idea that they were being fed a dummy signal. The truth was not revealed until March the following year, by which time several papers about the supposed sensational discovery of gravitational waves were poised for publication. "While the scientists were disappointed that the discovery was not real, the success of the analysis was a compelling demonstration of the collaboration's readiness to detect gravitational waves," Ligo reported at the time. But take a look at the visualisation of the faked signal, says Dr Kiriushcheva, and compare it to the image apparently showing the collision of the twin black holes, seen on the second page of the recently-published discovery paper. "They look very, very similar," she says. "It means that they knew exactly what they wanted to get and this is suspicious for us: when you know what you want to get from science, usually you can get it." The apparent similarity is more curious because the faked event purported to show not a collision between two black holes, but the gravitational waves created by a neutron star spiralling into a black hole. The signals appear so similar, in fact, that Dr Kiriushcheva questions whether the "true" signal might actually have been an echo of the fake, "stored in the computer system from when they turned off the equipment five years before"." http://www.thenational.ae/arts-life/the-review/why-albert-einstein-continues-to-make-waves-as-black-holes-collide#full
LIGO's 2010 dress rehearsal: A few "expert administrators" injected a false signal, deceived everybody, and misled astronomers into wasting time and money on the fake. Remarkably, "this became particularly useful starting in September 2015":
"...a blind injection test where only a select few expert administrators are able to put a fake signal in the data, maintaining strict confidentiality. They did just that in the early morning hours of 16 September 2010. Automated data analyses alerted us to an extraordinary event within eight minutes of data collection, and within 45 minutes we had our astronomer colleagues with optical telescopes imaging the area we estimated the gravitational wave to have come from. Since it came from the direction of the Canis Major constellation, this event picked up the nickname of the "Big Dog Event". For months we worked on vetting this candidate gravitational wave detection, extracting parameters that described the source, and even wrote a paper. Finally, at the next collaboration meeting, after all the work had been cataloged and we voted unanimously to publish the paper the next day. However, it was revealed immediately after the vote to be an injection and that our estimated parameters for the simulated source were accurate. Again, there was no detection, but we learned a great deal about our abilities to know when we detected a gravitational wave and that we can do science with the data. This became particularly useful starting in September 2015." https://www.researchgate.net/blog/post/a-null-result-is-not-a-failure
Consider the GW170817 (neutron-star-collision) event. Even if gravitational waves existed (they don't), the simultaneous arrival of optical signals and gravitational waves would remain an obvious fake, for the following two reasons:
1. That (some, not all) gravitational waves travel at the speed of light was Eddington's 1922 fabrication (nothing to do with Einstein's general relativity):
Arthur Eddington 1922: "The problem of the propagation of disturbances of the gravitational field was investigated by Einstein in 1916, and again in 1918. It has usually been inferred from his discussion that a change in the distribution of matter produces gravitational effects which are propagated with the speed of light; but I think that Einstein really left the question of the speed of propagation rather indefinite. His analysis shows how the co-ordinates must be chosen if it is desired to represent the gravitational potentials as propagated with the speed of light; but there is nothing to indicate that the speed of light appears in the problem, except as the result of this arbitrary choice. [...] Weyl has classified plane gravitational waves into three types, viz.: (1) longitudinal-longitudinal; (2)longitudinal-transverse; (3) transverse-transverse. The present investigation leads to the conclusion that transverse-transverse waves are propagated with the speed of light in all systems of co-ordinates. Waves of the first and second types have no fixed velocity - a result which rouses suspicion as to their objective existence." http://rspa.royalsocietypublishing.org/content/royprsa/102/716/268.full.pdf
2. The simultaneous arrival of optical signals and gravitational waves can only be discussed if the gravitational waves experience Shapiro delay, like optical signals, which is nonsense of course.
Conclusion: LIGO conspirators obviously FAKED the simultaneous arrival of optical signals and gravitational waves in the GW170817 (neutron-star-collision) experiment.
