A team of astrophysicists says they may have found evidence for “cosmic strings”, long-hypothesized defects in the universe left over from its early in its expansion.
Cosmic strings were first suggested in the 1970s by theoretical physicist Tom W. B. Kibble, and later revived in the context of string theory. The one-dimensional strings, far narrower even than a proton, are thought to have sprung into existence in the very first second of the universe and could potentially stretch right across it.
The strings, sometimes referred to as cracks in the universe, had not been detected since they were conceived, though there were a few ideas on how we might. When strings cross, for instance, it could provide us an opportunity to find them.
