CERN released the results indicating that in their experiment neutrinos cheated the speed of all speeds in September 2011. They were trying hard to explain that phenomenon, but now they confirmed the results were faulty due to faults in the test equipment. Sergio Bertolucci, CERN research director summarized the events with these words:
"The story captured the public imagination, and has given people the opportunity to see the scientific method in action - an unexpected result was put up for scrutiny, thoroughly investigated and resolved in part thanks to collaboration between normally competing experiments. That's how science moves forward."
What are neutrinos anyway? Neutrinos are one of the elementary particles of the universe. They travel at the speeds near to the speed of light, and unlike the electrons and other subatomic particles, do not have an electronic charge. Neutrinos are produced mostly by decay of particles, they travel alone abundance of them was produced at the early stages of creation of the universe. They are really tiny in mass, but there is a lot of them, that's why it is believed that they contribute to the total mass of the universe and have an effect on its expansion.
