Research physicists using a particle accelerator may have discovered a new force of nature. The team at the Tevatron is currently analysing its data before announcing it has found a previously-unknown particle.
“We’d essentially be saying there’s a new force of nature being communicated by the particle. We know that there’s four forces: electromagnetism, gravity, and the strong and weak nuclear forces. This would be the fifth; every freshman physics class would have to change their textbooks.”
