“In 1905, Poincaré first predicted gravitational waves (ondes gravifiques) emanating from a body and propagating at the speed of light as being required by the formalism of spacetime” from –
https://en.wikipedia.org/wiki/Henri_Poincar%C3%A9

Poincaré had created the special theory of relativity before Einstein, during the period 1895-1905, and he also investigated some other concepts that can be found in general relativity. This theory was generally known as the “Relativity of Poincaré and Lorentz” in those years. See http://www.brera.unimi.it/sisfa/atti/1998/Giannetto.pdf

I’m just going to add that beyond that, your comment is a poorly informed and delusional rant. You need to get some help. I am not joking.

Why didn’t LIGO simply wait for another signal? Would not waiting for a second signal detract from the chance of this being seen as scientific fraud perpetuated on the taxpayer?

Well, perhaps the best answer as to why LIGO did not wait for at least a second signal is that they were beginning to think they’d never see another one! And they panicked! They knew had to act fast so as to maximize their chances for optimal hype, funding, and hiring and tenure decisions. They couldn’t let any more time going by without seeing a signal, or otherwise it would look more and more like an unrepeatable anomaly, misinterpretation, noise, hoax, or prank. And once the multimillionaire funders decided on the press conference, what lowly postdoc is going to speak out against the regime’s decision, let alone the senior scientists who devoted their life to it?

The first supposed LIGO detection of two merging black holes happened just before they officially turned the LIGO machine on, on September 15th.

Since then, they have seen no other signals.

Imagine that you are on the LIGO team.

You “see” a supposed signal of a “binary black hole merger” before you officially turn the LIGO machine on on September 15th 2015.
You are elated as this means the Nobel Prize, tenure, billions in funding!
You then turn on the machine.
You see no other detections nor signals.
Months go by and no other signals are seen.
You begin to panic.
You realize that your window for major publicity and funding is closing fast.
Five months go by and no other signals are seen.
Panic sets in.
You pull the trigger to get massive funding and hopefully billions more in funding.
You hold a massive press conference on February 11th, hyping only one tiny event.
The world’s unquestioning useful idiot science bloggers all fall in line, hyping and regurgitating your spurious press releases as the gospel truth.
Kip Thorne solidifies it all stating that now we will finally be able to observe the pseudoscience of giant cosmic strings born of the pseudoscience of inflation.
Hundreds of millions of dollars of granting and hiring deciscions are made while hundreds of LIGO members receive tenure and promotions for merely falling in line on a project seeking evidence for a 100-year–old theory which already appears quite correct.
Another signal is never seen.
All the faulty blogs and wikipedia pages and tenure and funding deciscions remain, as once done, they are “impossible” to undo, according to the elite.
The unquestioning regime of billion-dollar corporate science is advanced, giving the middle finger to the lone patent examiner and humble physicists who did far, far more with a pencil, paper, logic, reason, and honor, sans the corporate state’s hype and lies.
So LIGO, when, if ever, will we see another “signal”?

There are other astronomical hazards out there for future deep space travelers. For example, gamma ray bursts from collapsing stars (another exemplar of mind-boggling energy release) will shoot out beams of x-rays and gamma rays strong enough and long enough to fry anything in its stellar neighborhood — including potentially sterilizing entire planets that might have the misfortune of lying in the beam path.

Those kinds of events would not be predictable in the way that star mergers would be. (Stars don’t telegraph their imminent collapse, an event which progresses rapidly, whereas we can observe and predict orbit decay.)

Fortunately, GRB’s are fairly rare, as stellar events go. “Outer space” is full of dangerous stuff, and “the safety of Earth” is relative…
