New study implies existence of fifth force of nature
Irvine, Calif. (UPI) May 26, 2016
A team of Hungarian physicists published a paper last year hinting at the possibility of a fifth force of nature. It escaped publicity, but a recent analysis of the data by researchers at the University of California, Irvine has brought the paper back into the limelight. The Standard Model of particle physics - a model that helps scientists explain all the physics we can observe - features four main forces: gravity, electromagnetism and the strong and weak nuclear forces. Scientists have long ... read more
