Gravitational waves spark hunt for cosmic strings and dark matter

Theoretical physicists have leapt upon the current discovery of a background hum of gravitational waves permeating the whole universe, with claims that the sign may very well be an indication of darkish matter and even shed new gentle on the earliest moments of existence.

“There was lots of pleasure within the high-energy physics neighborhood,” says Andrea Mitridate on the California Institute of Know-how, who’s a part of the group that found the gravitational wave background. “To be trustworthy, I’ve had …
