But the finding helps bring physicists closer to figuring out just what is wrong with the so-called Standard Model, their best \u2014 albeit incomplete \u2014 theory of the laws that rule the subatomic realm. One way physicists know it is not quite accurate is that it suggests that the neutrino should not have any mass at all.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">At grander scales, learning more about neutrinos will help cosmologists fill in their ever hazy picture of the universe, including how galaxies clustered together and <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2025\/03\/19\/science\/space\/astronomer-desi-dark-energy.html\" title=\"\">what influences the expansion<\/a> of the cosmos since the Big Bang.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">\u201cWe\u2019re looking at trying to understand why we are here,\u201d said John Wilkerson, a physicist at the University of North Carolina, Chapel Hill and an author of the new study. \u201cAnd that\u2019s something neutrinos may have a key role in.\u201d<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-1\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Physicists know a few things about neutrinos. They are prolific across the cosmos, created virtually anytime atomic nuclei snap together or rip apart. But they carry no electric charge and are <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2025\/02\/12\/science\/astrophysics-universe-neutrinos.html\" title=\"\">notoriously difficult to detect<\/a>.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Neutrinos also come in three types, which physicists describe as flavors. And, oddly, they morph from one flavor to another as they move through space and time, a discovery recognized by the <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2015\/10\/07\/science\/nobel-prize-physics-takaaki-kajita-arthur-b-mcdonald.html\" title=\"\">Nobel Prize in Physics in 2015<\/a>. The underlying mechanism that makes these transformations possible, physicists realized, meant that neutrinos must have some mass.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">But only just so. Neutrinos are mindboggingly light, and physicists don\u2019t know why. <\/p>\n<p class=\"css-at9mc1 evys1bk0\">Uncovering the exact values of the mass of neutrinos could lead to \u201csome kind of portal\u201d to new physics, said Alexey Lokhov, a scientist at the Karlsruhe Institute of Technology in Germany. \u201cThis is, for now, the world\u2019s best limit,\u201d he said of his team\u2019s measurement.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Dr. Lokhov and his colleagues used the Karlsruhe Tritium Neutrino, or KATRIN, experiment to narrow down the mass of a neutrino. At one end of the 230-foot-long apparatus was a source of tritium, a heavier version of hydrogen with two neutrons in its nucleus. Because tritium is unstable, it decays into helium: One neutron converts into a proton, which spits out an electron in the process. It also spits out an antineutrino, the <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2023\/09\/27\/science\/physics-universe-antimatter.html\" title=\"\">antimatter twin<\/a> of a neutrino. The two should have identical mass.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The mass of the original tritium is split among the products of the decay: the helium, electron and antineutrino. Neither neutrinos nor antineutrinos can be directly detected, but a sensor at the other end of the experiment recorded 36 million electrons, over 259 days, shed by the decaying tritium. By measuring the energy of the electron\u2019s motion, they could indirectly deduce the maximum mass possible for the antineutrino.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-2\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">They found that value to be no more than 0.45 electronvolts, in the units of mass used by particle physicists, a million times lighter than an electron.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The upper bound on the mass was measured for only one flavor of neutrino. But Dr. Wilkerson said that nailing down the mass of one makes it possible to calculate the rest.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The latest measurement pushes the possible mass of the neutrino lower than the <a class=\"css-yywogo\" href=\"https:\/\/www.nature.com\/articles\/s41567-021-01463-1\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">previous limit<\/a> set in 2022 by the KATRIN collaboration, of no more than 0.8 electronvolts. It is also nearly twice as precise.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Elise Novitski, a physicist at the University of Washington who was not involved in the work, commended the KATRIN team\u2019s careful effort.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">\u201cIt\u2019s really just a tour de force,\u201d she said of the experiment and the discovery. \u201cI have full confidence in their result.\u201d<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-3\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">The KATRIN team is working on an even tighter boundary on the neutrino mass from 1,000 days of data, which it expects to collect by the end of the year. That will give the physicists even more electrons to measure, leading to a more precise measurement.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Other experiments will also contribute to a better understanding of the neutrino\u2019s mass, including <a class=\"css-yywogo\" href=\"https:\/\/www.project8.org\/\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">Project 8<\/a> in Seattle and the <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2024\/08\/30\/science\/astrophysics-dune-neutrinos.html\" title=\"\">Deep Underground Neutrino Experiment<\/a>, spread across two physics facilities in the Midwest.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Astronomers studying the structure of the cosmos at large, thought to be influenced by the vast collection of neutrinos flooding the universe, have their own measurement of the particles\u2019 maximum mass. But according to Dr. Wilkerson, the boundaries set by astronomers staring out into the void don\u2019t match up with what particle physicists calculate in the lab, as they scrutinize the subatomic world.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">\u201cThere\u2019s something really interesting going on,\u201d he said. \u201cAnd the likely solution to that is going to be physics beyond the Standard Model.\u201d<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<p><script async
