Physicists are excited and say this could be a major breakthrough in our understanding of the universe. It all has to do with the behavior of sub-atomic particles called muons. Experiments at a lab near the US city of Chicago have shown that muons move at a rate that’s faster than expected – potentially unlocking the secrets of a previously undiscovered fifth force of nature.
