We reported on this blog last month that the laws of Physics had apparently been broken, as scientists at CERN had seemed to make neutrinos travel faster than the speed of light. Einstein’s theory of relativity – along with our entire understanding of the Universe – would have to be completely re-written.
This has turned out to be a controversial and unpopular finding; the validity and reliability of the test have been heavily questioned by Physicists. It is for this reason that the scientists at CERN are set to fine-tune and repeat the test, to make sure they haven’t just made a mistake.
In the original test, a beam of neutrinos were sent on a 720km underground journey from Geneva to San Grasso, and were recorded to turn up sixty-billionths of a second faster than a beam of light would have done. This led to the conclusion that the speed of light (the speed limit of the Universe) had been broken.
Professor Jim Al-Khalili, Physicist and TV presenter (pictured left), believes the result is an error and will be proved wrong. Summing up the general attitude of Physicists everywhere, he confidently announced to the media: “If the Cern experiment proves to be correct and neutrinos have broken the speed of light, I will eat my boxer shorts on live TV.”
The test is scheduled to be repeated before the end of this year. This gives the CERN scientists time to refine their method and calculations, and (as expected by many) conclude that neutrinos cannot travel faster than light. It also gives Professor Al-Khalili some time to invest in some chocolate boxer shorts, just in case.
