All of them (and possibly lots or fifty-fifty all of LIGO folks) are missing that the 2 LIGO detectors aren't predicted to run across signals that are just proportional to each other At a Forbes blog, Sabine Hossenfelder uncritically promotes a combative Danish newspaper inwards her article
ATdotDE together with discovered my ain LIGO gravitational wave. I am absolutely sure that the probability that such clear signal-like events hap past times run a jeopardy is negligible. Also, the gravitational waves are the exclusively conceivable signal that tin laissez passer on the sack brand the delay betwixt the 2 detectors this small. Any seismic or similar procedure would almost for certain atomic number 82 to a much longer delay, basically because the vibrations would spread through the globe past times the speed of audio etc.
Andrew Jackson et al. is proverb that "something is wrong" because "the relaxation dissonance from LIGO-LA together with LIGO-WA detectors are correlated together with possess got the same delay" but this correlation betwixt these 2 "noises" shouldn't exist.
Except that this disputation is wrong. The residuals aren't just noise. They're the divergence betwixt the best gibe together with the actual observation. But the best gibe isn't the same affair equally the actual gravitational wave.
In particular, equally I possess got emphasized from the real beginning, the 2 detectors – LIGO-LA together with LIGO-WA – are directed inwards somewhat unlike directions, together with thus they basically observe unlike polarizations of the gravitational wave. Because that gravitational moving ridge is rather full general – it is neither circularly polarized, nor linearly polarized – the 2 detectors that basically mensurate the linearly polarized components inwards 2 unlike directions must yield somewhat unlike signals.
