Just recently there was an experiment carried out in central Italy about Neutrinos. A neutrino is basically a small electrically neutral particle which is released after a nuclear reaction. In the experiment, they say that the Neutrino made a 731 kilometre run 60 nanoseconds faster than the speed of light. This caused an outbreak in the scientific community as it was known that light is the fastest thing known to us humans.
They also said that there was no flaw in their experiment until other organisations disproved that theory and suggested it was a timing error.
- To what extent can we trust things which are not exactly observable?
- How do we measure things accurately?
