The LIGO noise controversy

This story fits well into the problem of interpreting data and that even in the hardest experimental sciences, this can be tricky. Like in a rather recent story about gravitational wave detection. The gravitational waves which are measured have not always been reliably confirmed with electromagnetic data. This produced also some skeptic reactions.

A group of Danish scientists has voiced doubt of the results. News reports like here (Ars technica) or here (Quanta article by Natalie Wolchover) or more recently in ars technica report that there are ``no more doubts". There are some, who still want to see more evidence. This article by Sabine Hossenfelder in the German Heise news portal updates a bit on the dispute whether LIGO was really measuring gravitational waves and refers to a newer article of the Danish group. She mentions that also an announcement of August 17 on a black hole eating a Neutron star was not confirmed. Hossenfelder writes that the situation is unique in that the results are currently difficult to verify independently as the LIGO machine is the only one. The article of Hossenfelder finishes with some hope as in the December of this year, a Japanese interferometer KAGRA will join the search and hopefully make things even more clear.
