Who won the Nobel Prize in Physics at the end of the series?

Sheldon Cooper and Amy Farrah Fowler won the Nobel Prize in Physics at the end of The Big Bang Theory. Their award is revealed in the series finale, “The Stockholm Syndrome,” which originally aired on May 16, 2019.

The fictional prize recognizes the pair’s work on super-asymmetry, a theory they develop during the final seasons. Their research brings together Sheldon’s theoretical physics expertise and Amy’s background in neurobiology and later scientific collaboration with him. In the finale, the entire group travels to Sweden for the Nobel ceremony.

The award is the professional climax of Sheldon and Amy’s story, but the episode also emphasizes personal growth. Sheldon initially focuses almost entirely on the ceremony and his own achievement. During his acceptance speech, he thanks his friends, family and wife, acknowledging that their support helped make his success possible. The finale also reveals Penny’s pregnancy and shows Sheldon and Amy wearing their Nobel medals.
