We'd be flying at the speed of light without the Higgs boson slowing us down
hue Muons are heavy cousins of electrons that rain down on Earth from cosmic ray collisions in the upper atmosphere.
Fun Fact

hue Neutrinos are nearly massless leptons that rarely interact with normal matter, making them incredibly hard to detect.
Glossary
lepton (noun)
Any of a family of subatomic particles, including electrons and neutrinos, that do not experience the strong force. Léon Rosenfeld coined the term in 1948, deriving it from the Greek word for small or thin.
