Theoretical physicists at the University of California at Irvine say there may be evidence for a fifth fundamental force of nature. If this were true, it would be one of the most revolutionary scientific discoveries in history and could help explain anomalies like dark matter and dark energy.
The physicists say the new discovery came about while searching for dark photons. They found a “radioactive decay anomaly” that suggests the existence of a new particle they’re calling “protophobic X boson.”
Jonathan Feng, professor of physics & astronomy, says the evidence suggests this particle is neither a matter particle nor a force carrying particle and could be an entirely new kind of phenomenon previously unknown to science. Feng, who believes that dark matter could constitute its own realms, says the discovery could put us on the path to discovering a fifth fundamental force of nature that ties together the strong and weak nuclear, electromagnetic, and gravity as “manifestations of one grander, more fundamental force.”
