From subatomic particles to complex molecules, quantum systems hold the key to understanding how the universe works. But there's a catch: when you try to model these systems, that complexity quickly ...
Physicists have set a new upper limit on the mass of neutrinos. And the finding could poke a big hole in the Standard Model of particle physics. When you purchase through links on our site, we may ...
Physicists have scaled down the maximum possible mass of an elusive "ghost particle" called a neutrino to at least one-millionth the weight of an electron. The revision takes scientists one more step ...
