A coworker earlier mentioned a paper questioning the validity of the findings around gravitational waves. Can anyone point me to them and (as a non-scientist) explain why this paper would think those findings are inaccurate?
- batmansmk 9y agoCan you coworker provide some info instead?
- dpcx 9y agoHe could provide information about the paper, sure. The explanation, I'm fairly certain, he could not.

The problem with the analysis in the paper that questioned LIGO's results was that they misinterpreted the filtering that had been applied to the data shown in the original GW150914 paper, which led them to think there was noise produced by the detectors themselves.

- InclinedPlane 9y agoYour coworker might be confusing the LIGO observations (widely considered to be some of the most meticulously done research in science) with the BICEP2 early big bang gravitational wave research, which has since been called into question substantially.
