Italian scientists say neutrinos can travel faster than light. If this is proven to be true what does it say about relativity and causality...
I have just read an article that quite frankly causes my mind to spin in circles. First let me say that I am no astrophysicist, or even that smart when it comes to mathematics, but I have a hard time getting my head around this. Maybe some of readers can figure this out better than I can.
It all starts with an article in Nature News. They report that an Italian experiment has found that neutrinos can travel faster than light. They are studying neutrinos coming from CERN – 730 Km away from their lab and they claim that they are arriving 60 nS faster than the speed of light would allow. Now their facts haven’t been checked yet – so this could all be a publicity stunt.
For one minute let’s assume it is true. First we would need Einstein back to update many of his equations. But relativity assumes that there is a reference in which things in time can be placed – relative to – each other. This gives us the basis for causality. Now if this is not true, then it means that causality has been shot in the head. In their experiment, it means that if we were to move the detector closer to CERN, then at some point the neutrinos would not be detected “earlier” than expected but before they were generated. Huh?? Does this mean that it would be possible to go to the Restaurant at the end of the Universe, watch the big bang or go for a ride in the Tardis? Where do I book?
