"War" in the world of gravitational science



[ad_1]

While gravitational waves propagate like space-time ripples from the depths of space, crossing Earth and Earth, the doubts of some scientists about whether gravitational waves have actually been discovered have started to permeate the international scientific community.

In February 2016, the gravitational wave laser interferometer (LIGO) observatory announced that its two detectors located in the United States had detected the first gravitational waves of the universe in 2015, after years of experimentation, thus confirming experimentally the theory of existence. based on the theory of general relativity of Einstein. The international impact has been important. The discovery was hailed as one of the most important of the last century and, as expected, the principal investigators won the Nobel Prize in Physics in 2017. Since then, gravitational waves have been detected five times. Or maybe not?

The shadows appeared above the discovery, so much so that, according to the skeptics, it was not a discovery. Nobel was therefore ashamed! Admittedly, this has not been confirmed and LIGO's scientific team strongly defends its discovery, but skeptics have their own counter-arguments.

A team of physicists from the Copenhagen Nils Bore Institute, which has been carrying out a separate badysis of experimental data for two and a half years, claims that the trace of the gravitational waves captured by the LIGO detectors is only an illusion due to so-called "noise" detectors. . Detector laser measurements are indeed extremely difficult because they involve incredibly subtle space-time rifts from gravitational waves, in the order of a billionth of a billionth of a diameter.

Opponents, who appeared for the first time in 2017 and are now returning, consider that the supposed gravitational wave measurement was not a real gravitational signal but was due to the natural thermal vibrations that constitute the "noise". Danish scientists have expressed doubts about the accuracy of the measurements and presented them in scientific publications. The LIGO team has not responded yet.

"We believe that LIGO has not been able to convincingly present the detection of gravitational incidents up to now," Jackson's "heretical" representative told New Scientist, who said discovered the controversy.

In response, LIGO indicated that it was going to publish a detailed explanation of how it badyzes the "noise" of its detectors, although it did not specify when this would occur.

Other scientists have attacked the challengers, blaming them that their criticisms were not convincing and not the gravitational waves detected. "Many people have looked at their badysis and concluded that their claims are completely unfounded," said Caltech's Caltech Institute of Technology's David Caltech, who also accused the well-known scientist New Scientist of a "highly discriminatory" publication. .

LIT representative, David Summer of the MIT University, said that there was a misunderstanding regarding LIGO's data badysis methods. "Skepticism is really good in science, you have to question the results, but we're dealing with complex data here, not just about understanding, but nothing Jackson and his team say gives us reason to doubt. of our discoveries, "he said.

"The badysis of the Danes is simply wrong," said Neil Cornies, data badyst at Ligo, Montana State University.

It is certain that the Danish opinion is a large minority among natural persons, most of them in favor of LIGO, even if they would not see bad eyes and would confirm the discovery by another independent badysis. .
