That said, CBS is determined to cross The Big Bang Theory over with Young Sheldon this December, and the prequel series' co-creator sees no reason why more crossovers can't happen in the future.

This is the kind of casting stunt that causes universes to explode: Young Sheldon titular star, Iain Armitage, is set to invade Adult Sheldon's (Jim Parsons) universe via a guest appearance on an upcoming episode of The Big Bang Theory, TVLine has learned.

When the show began in 2007, the main cast was made up of Jim, Kaley Cuoco, Johnny Galecki, Kunal Nayyar and Simon Helberg.

The Big Bang Theory airs Thursdays at 8 PM, followed by Young Sheldon at 8:30 PM on CBS.

As the show has gone on, becoming the longest-running multi-cam series ever, it added Mayim Bialik, Melissa Rauch and Kevin Sussman as regulars.

Ever since The Big Bang Theory spin-off prequel Young Sheldon premiered past year, the shows' producers have been open about their intentions to get the two shows to intersect.

What we do know for sure about the crossover is that, alongside Armitage as little Sheldon, Lance Barber and Montana Jordan will cameo as their respective characters George Cooper Sr., Sheldon's father, and George "Georgie" Cooper, Jr., Sheldon's brother.

The Big Bang Theory is set to finish at the end of season twelve, which will wrap up in 2019. "We, along with the cast, writers and crew, are extremely appreciative of the show's success and aim to deliver a final season, and series finale, that will bring The Big Bang Theory to an epic creative close".
