There could be a new force of nature to be reckoned with in the universe. According to theoretical physicists at UC Irvine, there is evidence of a fifth fundamental force of nature. If the force exists, it seems to be carried by a particle that had been unnoticed until very recently. The researchers published their theory in the journal called Physical Review Letters, with a follow up study posted on arXiv. If their theory is correct, it could alter everything known about the standard model of particle physics.
The 4 Forces of Nature
The current model of physics acknowledges four known forces that govern how matter interacts. They are gravitation, strong nuclear force, weak nuclear force and electromagnetism. Gravitation shapes the universe on a grand scale – think galaxy – while the nuclear forces have to do with the miniscule interactions between subatomic particles. The four forces thus govern the entirety of matter interactions in the universe.
The Boson X
The UC Irvine research team says that there may be evidence of a fifth force which has been carried on a particle which they have christened as “boson X.” The force would be a companion to electromagnetism, except that the force works between electrons and neutrons. Electromagnetism is about how electrons and protons are involved. Protons theoretically do not play a role in the “boson X” concept.
“If this is true, it would be a really big guide as to what the future would hold as far as the ultimate theory of particle physics,” said Timothy Tait, a UC Irvine theoretical particle physicist and co-author of the study.
Scientists have long acknowledged that what they know about the makeup of the universe is weak compared to what they do not know. The UC Irvine researchers came upon their hunch after reading a Hungarian paper, whose researchers were searching for a dark photon. The Hungarians found a weird signal in the data. The UC Irvine team said the signal was not a photon, but could actually be from a previously unknown boson.
One of the major questions for physicists is the issue of dark matter. Dark matter does not interact with other matter, yet it makes up around 27 percent of the universe’s mass-energy density. Consequently, dark energy comprises more than 68 percent of the universe. That’s a lot of uncharted territory for physicists to look at.
Although the researchers are cautious, they also hope that the discovery could help usher in a new era for scientific study of dark matter. If the scientists are correct, then the discovery could itself be the dark force that interacts with dark matter over small scales. Such a conclusion would of course be the product of intense and long studies. Still, the potential for upending the known universe is certainly there.
