Today’s Final Jeopardy Answer, October 17, 2025, Friday

On October 17, 2025, Friday, Jeopardy! presented its audience with an intriguing science question for the Final Jeopardy round. 
In 1930, physicist Wolfgang Pauli proposed a mysterious particle. It was found in 1956 after decades of speculation and study. This scientific question should be answered "What is the neutrino?" This milestone in physics shows how scientific theories have evolved and how we study invisible phenomena.

Wolfgang Pauli proposed the neutrino, an undetectable particle, to explain the beta decay energy differences. Scientists noticed that this process emitted energy that did not match energy conservation. Pauli proposed that a "neutron," an undetectable particle, was responsible for the missing energy. Years later, "neutrino" was coined, and the Cowan-Reines experiment confirmed its existence in 1956. The discovery transformed particle physics and led to the study of neutrinos' role in cosmic events.
