Overlooked particle may explain how matter gained an edge over antimatter after the Big Bang

Summary

Scientists have proposed a new theory that the early universe was shaped by an ancient particle that has been overlooked for decades. According to 404 Media, the particle might have given matter an edge over antimatter in the split-seconds after the Big Bang, and researchers say this "could transform our understanding of cosmic evolution and the fundamental laws of physics." Phys.org reports the same theory on the birth of the cosmos, describing the particle as the force that shaped the early universe. Both reports present the idea as a new theory, and neither summary describes independent confirmation.
