The impossible particle that saved the laws of physics
In short: In 1930, Wolfgang Pauli did something theorists were forbidden to do: he invented a particle out of thin air. This lecture explores how his 'imaginary' solution became one of our most vital tools for understanding the universe.
To preserve the principle of energy conservation during certain radioactive decays, Pauli proposed the existence of a particle so small it was deemed undetectable. This hypothetical entity, the neutrino, was later proven to exist in 1956.
Today, neutrinos are essential for probing the cosmos. They are detected in Antarctic ice and deep underground water tanks to reveal the physics of supernovae, dark matter, and the origins of the Big Bang.
