“Seekers of gravitational waves are on a cosmic scavenger hunt.
Since the Advanced Laser Interferometer Gravitational-wave Observatory turned on in 2015, physicists have caught these ripples in spacetime from several exotic gravitational beasts — and scientists want more.
This week, LIGO and its partner observatory Virgo announced five new possible gravitational wave detections in a single month, making what was once a decades-long goal almost commonplace (SN Online: 5/2/19)….
….“We’d be surprised if they didn’t exist, but we haven’t seen one” of these combinations, says LIGO team member Christopher Berry of Northwestern University in Evanston, Ill.”
