BINGE RAMPAGE The Sheldon-verse
← Hub

One family, one physicist, one very big bang.

What started as four friends and a girl across the hall grew into a whole connected universe. A prequel about a boy genius in Texas. A spin-off about his big brother's shotgun marriage. And now a science-fiction swing about the guy who ran the comic book store. It's all one continuity — browse every series here, then flip to Chronological for the in-universe story in order, Release Order to see how the shows overlapped as they aired, or the Cooper Family Tree to trace the bloodline from Meemaw to CeeCee.

The Big Bang Theory franchise — one connected universe
All four shows share one canon. Young Sheldon and Georgie & Mandy are prequels/sequels to The Big Bang Theory; Stuart Fails to Save the Universe is the newest spin-off and hasn't aired yet (HBO Max, July 23, 2026) — its details are still under wraps.

The whole saga, in order.

From a nine-year-old Sheldon starting high school in 1980s Texas to a Nobel Prize in Pasadena and a leap into the multiverse — key beats across all four shows on one spine. Each beat is colored by the series it comes from and carries a confidence score.

⚠️
The franchise is deliberately loose about exact years in the 1990s (CeeCee's birth, Georgie's age and Sheldon's age at his father's death don't perfectly line up across shows). Those beats are dated by best on-screen evidence and carry lower confidence on purpose — not false precision. Stuart's beat is pre-release and speculative.

How it aired — and how it overlapped.

The honest airing frame: each show is a long run, and they overlapped on purpose. Young Sheldon launched while The Big Bang Theory was still on; Georgie & Mandy launched the season Young Sheldon ended; Stuart arrives next. Tap any bar to see the show. series tracked.
