Gravitational waves spark hunt for cosmic strings and dark matter

Theoretical physicists have leapt upon the latest discovery of a background hum of gravitational waves permeating the complete universe, with claims that the sign could possibly be an indication of dark matter and even shed new mild on the earliest moments of existence.

“There has been a lot of excitement in the high-energy physics community,” says Andrea Mitridate on the California Institute of Technology, who’s a part of the group that found the gravitational wave background. “To be trustworthy, I’ve had …
