What is The Big Bang Theory?

Created by Chuck Lorre and Bill Prady, The Big Bang Theory follows physicists Leonard Hofstadter and Sheldon Cooper as their structured lives collide with Penny’s more social worldview. Over time, the group expands and evolves, turning nerd culture, comic books, sci-fi fandom, and academic ambition into comedic fuel.

The show is famous for weaving science into everyday jokes — not as decoration, but as a core part of the humor. That’s why TBBT trivia is so satisfying: the best questions test both your memory and your ability to catch references.
