We’ve just doubled the number of gravitational waves we can find: Nearly imperceptible quantum flickers used to limit how precisely we could detect the way space-time ripples, but squeezing the laser light used in detectors overcomes this and doubles the number of gravitational waves we can see

The headline is maybe a bit disingenuous, the technique they’re talking about has been used throughout the current LIGO observing run, which started over a year ago. So we haven’t “just” doubled the number we can find. Though this is still a very nice improvement.
Hey, I live near the virgo accelerator, they organize open visits for the general public from time to time, it’s very cool
