In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...

Neutrinos are known for funny business. Now scientists have set a new limit on a quantum trait responsible for the subatomic particles’ quirkiness: uncertainty. The lightweight particles morph from ...

Peter Higgs, who gave his name to the subatomic particle known as the Higgs boson, passed away at the age of 94. He was always a modest man, especially when considering that he was one of the greats ...
