New research published in the journal Science has revealed the most precise measurement to date of the upper limit of a neutrino’s mass, bringing physicists closer to understanding the flaws in the Standard Model of physics. Neutrinos, elusive particles that are abundant in the universe, were previously thought to have no mass at all, but recent findings suggest otherwise.
Neutrinos come in three flavors and can transform from one to another as they travel through space and time. The discovery that neutrinos have some mass has puzzled physicists, as these particles are incredibly light. The recent measurement, conducted by the Karlsruhe Tritium Neutrino experiment, found the maximum possible mass of a neutrino to be no more than 0.45 electronvolts.
While the exact mass of a neutrino remains unknown, this new measurement is a significant step forward in understanding these mysterious particles. Future experiments, such as Project 8 in Seattle and the Deep Underground Neutrino Experiment, will contribute to further unraveling the neutrino’s secrets.
According to experts, the discrepancy between the neutrino’s mass as observed by astronomers studying the universe at large and as calculated by particle physicists in the lab indicates the presence of physics beyond the Standard Model. The ongoing research into neutrinos could potentially lead to groundbreaking discoveries that reshape our understanding of the fundamental laws that govern the universe.
