Textbooks might have to be rewritten if fifth fundamental force of nature is true

An awful lot of textbooks might have to be rewritten if the claim of theoretical physicists at the University of California, Irvine, that it’s possible they've come across evidence of a fifth force that could help shine a light into the dark corners of the universe turns out to be true.

So far, scientists had been claiming the existence of only four forces that hold very reality of humanity together. Of these, we mainly interact with two fundamental forces daily. While gravity keeps you from being propelled toward the horizon by even the most casual fist bump, electromagnetism facilitates you to read these words right now.

In a news release Monday, Jonathan Feng, professor of physics and astronomy at UC Irvine, said it would be revolutionary if the fifth force turns out to be true. If confirmed by further experiments, this discovery of a possible fifth force would completely change our understanding of the universe, with consequences for the unification of forces and dark matter, said Feng.

"The experimentalists weren't able to claim that it was a new force," Feng said. "They simply saw an excess of events that indicated a new particle, but it was not clear to them whether it was a matter particle or a force-carrying particle."

Delving on what the fifth force is in case it does exist, scientists say at this point of time they do not really know much about it. Hunting in this direction, some Hungarian experimental nuclear physicists were looking for so-called "dark photons," a hypothetical particle that could be linked to the elusive dark matter that is believe to form 85% of the universe.

So if the experiments prove true, there could be a miniscule fifth force that might be the bridge between our current understanding of particle physics and the unseen "dark" sector of physics that accounts for things like dark matter.
