Also a physicist. I may have let my passion for what the guys at virgo have been up to bias my judgment - visited years ago when they were commissioning the place, and had a long, long discussion about the problems they overcame, mostly around optics and noise, which they shared solutions for with the ligo folks. Now the paper is out I&#x27;ve untwisted my knickers as I can see they&#x27;ve cited the teams around the globe. The media up until that point kinda gave the impression it was a sole effort.<p>Giant&#x27;s shoulders and all that.
