Did the rapid cooling of the universe crack the entire fabric of spacetime? Everything says it should have, but why can't we find these elusive "cosmic strings"?

Galaxy-Size Gravitational-Wave Detector Hints at Exotic Physics Recent results from a pulsar timing array, which uses dead stars to hunt for gravitational waves, has scientists speculating about cosmic strings and primordial black holes Print Representative illustration of Earth embedded in spacetime that is deformed by the background gravitational waves and its effects on radio signals coming from observed pulsars.

Cosmic Ringtones in Pulsar Data? January 28, 2021• Physics 14, 15 A pulsar survey has detected a potential signal from low-frequency gravitational waves, which theorists are eager to explain. Tonia Klein/NANOGrav By monitoring the radio flashes from distant pulsars, astronomers have spotted a signal that could be the result of a background of gravitational waves.
