If I were conspiratorially minded, I would say they are covering up an uncorrected relativistic effect with a bogus story of a hardware error. It would mean that the antineutrino emitted by one nucleus could, hypothetically, be absorbed (as a neutrino) by the other nucleus, and youd be able to get a decay where: There are currently multiple experiments, including the MAJORANA experiment, looking specifically for this neutrinoless double beta decay. The three types of neutrino almost certainly have different masses from one another, where the heaviest a neutrino is allowed to be is about 1/4,000,000th the mass of an electron, the next-lightest particle. The neutrino was first proposed in 1930, when a special type of decay beta decay seemed to violate two of the most important conservation laws of all: the conservation of energy and the conservation of momentum. This means that the shift can only be detected statistically, and it makes the result extremely vulnerable to unanticipated systematic errors, e.g., correlations between the time of emission of the neutrinos and their energy (which strongly affects the efficiency of detection) or the direction of emission. Axolotls and capybaras are TikTok famousis that a problem? a neutrino) would we be able to measure a higher speed. Until i hear or read any counter-claims to that paper, i'll consider this to be a settled matter. However, slow-moving neutrinos cannot produce a detectable signal in this fashion. But for right now, with current technology, the only neutrinos (and antineutrinos) we can detect via their interactions move at speeds indistinguishable from the speed of light. When an atomic nucleus decayed in this fashion, it: When you added up the energy of the electron and the energy of the post-decay nucleus, including all the rest mass energy, it was always slightly less than the rest mass of the initial nucleus. One popular discussion is of "Faster than light propulsion". Either they are wrong about either the distance (mismeasurement, or there is a spacetime "rift" within the Earth :-P) or the time (clock synchronization error or drift), or they have actually discovered superluminal neutrinos. Neutrinos and antineutrinos come in a wide variety of energies, and the odds of having a neutrino interact with you increase with a neutrinos energy. How this animal can survive is a mystery. A high level description of the problem is given here and a more detailed explanation of the investigation is here. Neutrino 'faster than light' scientist resigns - BBC News
