A Kerr loop created from superstring material, forming a temporal rift
A Kerr loop was a temporal phenomenon which could be created through the interactions of high-energy discharges with superstring material.
In 2344, a temporal rift which was the formation of a Kerr loop from superstring material, was created through the intense weapons fire in a battle between the USS Enterprise-C and four Romulan Warbirds at the Klingon outpost at Narendra III. The Enterprise-C was inadvertently responsible for the creation of an alternate timeline when it drifted into the rift and traveled through time. (TNG: "Yesterday's Enterprise")
