Default Albert Einstein Institute and Nonexistent Gravitational Waves

New Supercomputer "Minerva" Will Calculate Gravitational Waves Faster. Press Release From: Albert Einstein Institute

My comment on the article:

Neutron star mergers are far more likely than black hole mergers and yet LIGO haven't reported even weak and inconclusive signals (which could be compared with Integral's data and become valid evidence in the end):

http://www.lastwordonnothing.com/201...m-wow-to-yawn/
"What surprised the LIGO collaboration instead was the nature of what they'd detected. Of the various gravitational-wave-producers that LIGO might observe—the kind that disturb space-time to such an extent that LIGO could register the aftershock—the collision of binary black holes was perhaps the least likely. Supernovae, neutron stars, colliding neutron stars: These were what the LIGO collaboration foresaw as far more common candidates. And now LIGO has detected a second pair of colliding black holes."

http://www8.nationalacademies.org/ss...ay.aspx?id=146
"Advanced LIGO is likely to observe mergers of double neutron star (NS/NS) binaries at a rate of a few to a few hundred per year; and black-hole/neutron-star (BH/NS) binaries perhaps in a comparable range of rates." Benjamin J. Owen Pennsylvania State University, Endorsed by: David H. Reitze (University of Florida), Stanley E. Whitcomb (LIGO-Caltech)

http://aasnova.org/2016/10/26/narrow...ve-detections/
"Just over a year ago, LIGO detected its first gravitational-wave signal: GW150914, produced when two black holes merged. While we didn't expect to see any sort of light-based signal from this merger, we could expect to see transient electromagnetic signatures in the case of a neutron star–black hole merger or a neutron star–neutron star merger — in the form of a kilonova or a short gamma-ray burst. While we haven't yet detected any mergers involving neutron stars, LIGO has the sensitivity to make these detections..."

http://www.esa.int/Our_Activities/Sp..._bl ack_holes
"Models predict that the merging of two stellar-mass black holes would not produce light at any wavelength, but if one or two neutron stars were involved in the process, then a characteristic signature should be observable across the electromagnetic spectrum. Another possible source of gravitational waves would be an asymmetric supernova explosion, also known to emit light over a range of wavelengths. [...] Integral is sensitive to transient sources of high-energy emission over the whole sky, and thus a team of scientists searched through its data, seeking signs of a sudden burst of hard X-rays or gamma rays that might have been recorded at the same time as the gravitational waves were detected. "We searched through all the available Integral data, but did not find any indication of high-energy emission associated with the LIGO detection,"..."

Conclusion: Gravitational waves don't exist. LIGO's 2015 "discovery" was a fake - the dress rehearsal took place in 2010:

https://www.researchgate.net/blog/po...-not-a-failure
"Finally, how do you know you are doing something correctly if you have never done it before? That was a concerning question during Initial LIGO since we had never detected a gravitational wave before. How do we know our data analyses are not missing them? And, when we do detect one, how do we know that the science we have extracted from the signal is reliable? The answer is to do 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."

Note that in 2010 "a select few expert administrators" deceived everybody, misled astronomers into wasting time and money on the fake, and "this became particularly useful starting in September 2015"!

Another comment on the Albert Einstein Institute's publication (it will be deleted perhaps):

It would be interesting to know how many fudge factors LIGO introduced to make general relativity predict the nonexistent gravitational waves. Fudge factors are unjustified in deductive science but belong to the essence of the empirical (inductive) approach:

https://www.marxists.org/reference/a...ative/ap03.htm
Albert Einstein: "From a systematic theoretical point of view, we may imagine the process of evolution of an empirical science to be a continuous process of induction. Theories are evolved and are expressed in short compass as statements of a large number of individual observations in the form of empirical laws, from which the general laws can be ascertained by comparison.. Regarded in this way, the development of a science bears some resemblance to the compilation of a classified catalogue. It is, as it were, a purely empirical enterprise. But this point of view by no means embraces the whole of the actual process ; for it slurs over the important part played by intuition and deductive thought in the development of an exact science. As soon as a science has emerged from its initial stages, theoretical advances are no longer achieved merely by a process of arrangement. Guided by empirical data, the investigator rather develops a system of thought which, in general, is built up logically from a small number of fundamental assumptions, the so-called axioms."

Special relativity was indeed "built up logically from a small number of fundamental assumptions" (even though a false assumption and an invalid argument spoiled it from the very beginning) but general relativity was, to use Einstein's words, "a purely empirical enterprise". Einstein and his mathematical friends changed and fudged equations countless times until "a classified catalogue" was compiled where known in advance results and pet assumptions (such as the Mercury's precession, the equivalence principle, gravitational time dilation) coexisted in an apparently consistent manner. Being an empirical concoction, general relativity allows Einsteinians to introduce, change and withdraw fudge factors until the "theory" manages to predict anything Einsteinians want. Then the prediction turns out to be confirmed by observations (surprise surprise):

https://en.wikipedia.org/wiki/Fudge_factor
"A fudge factor is an ad hoc quantity introduced into a calculation, formula or model in order to make it fit observations or expectations. Examples include Einstein's Cosmological Constant..."

http://discovermagazine.com/2004/sep...ters-mistakes/
"In 1916 Einstein found what he considered a glitch in his new theory of general relativity. His equations showed that the contents of the universe should be moving - either expanding or contracting. But at the time, the universe seemed the very definition of stasis. All the data, facts, and phenomena known in the early 1900s said that the Milky Way was the cosmos itself and that its stars moved slowly, if at all. Einstein had presented the definitive version of the general theory of relativity to the Prussian Academy of Sciences the previous year, and he was not inclined to retract it. So he invented a fudge factor, called lambda, that could function mathematically to hold the universe at a standstill. [...] Lambda, also known as the cosmological constant, has come in handy of late."

http://www.amazon.com/Magnificent-Un.../dp/0684845946
Ken Croswell, Magnificent Universe, p. 179: "Ever since, the cosmological constant has lived in infamy, a fudge factor concocted merely to make theory agree with observation."

Two more examples of successful fudging:

1. By introducing NEGATIVE acceleration of light falling towards the source of gravity (the speed of falling photons DECREASES, unlike the speed of ordinary falling bodies which increases), Einstein and his mathematical friends made relativity predict the gravitational redshift, a prediction originally made by Newton's emission theory of light:

http://www.speed-light.info/speed_of_light_variable.htm
"Einstein wrote this paper in 1911 in German. [...] ...you will find in section 3 of that paper Einstein's derivation of the variable speed of light in a gravitational potential, eqn (3). The result is: c'=c0(1+φ/c^2) where φ is the gravitational potential relative to the point where the speed of light c0 is measured. Simply put: Light appears to travel slower in stronger gravitational fields (near bigger mass). [...] You can find a more sophisticated derivation later by Einstein (1955) from the full theory of general relativity in the weak field approximation. [...] Namely the 1955 approximation shows a variation in km/sec twice as much as first predicted in 1911."

http://www.einstein-online.info/spot...t_white_dwarfs
Albert Einstein Institute: "One of the three classical tests for general relativity is the gravitational redshift of light or other forms of electromagnetic radiation. However, in contrast to the other two tests - the gravitational deflection of light and the relativistic perihelion shift -, you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices. [...] The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..."

2. Michel Janssen describes endless empirical groping, fudging and fitting until "excellent agreement with observation" was reached:

https://netfiles.umn.edu/users/janss...0page/EBms.pdf
Michel Janssen: "But - as we know from a letter to his friend Conrad Habicht of December 24, 1907 - one of the goals that Einstein set himself early on, was to use his new theory of gravity, whatever it might turn out to be, to explain the discrepancy between the observed motion of the perihelion of the planet Mercury and the motion predicted on the basis of Newtonian gravitational theory. [...] The Einstein-Grossmann theory - also known as the "Entwurf" ("outline") theory after the title of Einstein and Grossmann's paper - is, in fact, already very close to the version of general relativity published in November 1915 and constitutes an enormous advance over Einstein's first attempt at a generalized theory of relativity and theory of gravitation published in 1912. The crucial breakthrough had been that Einstein had recognized that the gravitational field - or, as we would now say, the inertio-gravitational field - should not be described by a variable speed of light as he had attempted in 1912, but by the so-called metric tensor field.. The metric tensor is a mathematical object of 16 components, 10 of which independent, that characterizes the geometry of space and time. In this way, gravity is no longer a force in space and time, but part of the fabric of space and time itself: gravity is part of the inertio-gravitational field. Einstein had turned to Grossmann for help with the difficult and unfamiliar mathematics needed to formulate a theory along these lines. [...] Einstein did not give up the Einstein-Grossmann theory once he had established that it could not fully explain the Mercury anomaly. He continued to work on the theory and never even mentioned the disappointing result of his work with Besso in print. So Einstein did not do what the influential philosopher Sir Karl Popper claimed all good scientists do: once they have found an empirical refutation of their theory, they abandon that theory and go back to the drawing board. [...] On November 4, 1915, he presented a paper to the Berlin Academy officially retracting the Einstein-Grossmann equations and replacing them with new ones. On November 11, a short addendum to this paper followed, once again changing his field equations. A week later, on November 18, Einstein presented the paper containing his celebrated explanation of the perihelion motion of Mercury on the basis of this new theory. Another week later he changed the field equations once more. These are the equations still used today. This last change did not affect the result for the perihelion of Mercury. Besso is not acknowledged in Einstein's paper on the perihelion problem. Apparently, Besso's help with this technical problem had not been as valuable to Einstein as his role as sounding board that had earned Besso the famous acknowledgment in the special relativity paper of 1905. Still, an acknowledgment would have been appropriate. After all, what Einstein had done that week in November, was simply to redo the calculation he had done with Besso in June 1913, using his new field equations instead of the Einstein-Grossmann equations. It is not hard to imagine Einstein's excitement when he inserted the numbers for Mercury into the new expression he found and the result was 43", in excellent agreement with observation."

Being an empirical concoction, Einstein's general relativity has no postulates:

https://www.quora.com/What-are-the-p...ral-Relativity
What are the postulates of General Relativity? Alexander Poltorak, Adjunct Professor of Physics at the CCNY: "In 2005 I started writing a paper, “The Four Cornerstones of General Relativity on which it doesn’t Rest.” Unfortunately, I never had a chance to finish it. The idea behind that unfinished article was this: there are four principles that are often described as “postulates” of General Relativity:

1. Principle of general relativity

2. Principle of general covariance

3. Equivalence principle

4. Mach principle

The truth is, however, that General Relativity is not really based on any of these “postulates” although, without a doubt, they played important heuristic roles in the development of the theory." [end of quotation]
