Everything You Need to Know About The Big Bang Theory Season 12

This may or may not be the show's last hurrah

Liam Mathews

The Big Bang Theory ended its eleventh season last week with Sheldon (Jim Parsons) and Amy's (Mayim Bialik) wedding, which had us laughing and crying. And now, with that long-awaited event out of the way, our anticipation turns to Season 12.

Here's what we know so far. We'll keep updating this article as we find out more.

Season 12 might be the final season. The cast's (incredibly lucrative) contracts are up after Season 12, and the actors seem at peace with that. "The only manner in which the cast has discussed wrapping [The Big Bang Theory] has been that we're all going to be very sad when that day comes," star Johnny Galecki said in January. "But I think at this point everyone's very comfortable with 12 seasons being a good time to go home and see our families."

But CBS wants to keep the high-rated show on the schedule. "As long as [co-creator] Chuck [Lorre] and his team think they have stories tell, we're on board," said Thom Sherman, CBS Senior EVP of Programming. "We hope to get at least two more years out of them. [The Big Bang Theory] is not slowing down anytime soon." (It's worth noting that Warner Bros., not CBS, owns The Big Bang Theory, and the studio negotiates with producers and actors.)

It sounds like the producers have the option to end the show on their own terms when they want. It could be at the end of this season, it could be in 2021, it could be when flying cars have finally been invented. Whenever it is, Jim Parsons will look the same.

There will be more Young Sheldon crossovers. The spin-off has opened up what executive producer Steven Molaro calls a "unique time portal" where characters from Sheldon's childhood can grow up and head to The Big Bang Theory. One of those characters showed up in Season 11 in the form of Jerry O'Connell as Sheldon's brother George Jr. And Molaro told TV Guide that more might be coming, like young Sheldon's friend Tam.

As for the other direction -- Big Bang to Young Sheldon -- that's a little harder to pull off, but don't rule it out. "If we found the right story that worked for both shows it could happen," Holland told Deadline.

Don't expect any more babies. Now that Leonard (Johnny Galecki) and Penny (Kaley Cuoco) and Sheldon and Amy are married, fans are expecting more babies than Howard (Simon Helberg) and Bernadette's (Melissa Rauch) two. But don't get your hopes up.

"I think we're at our baby quota," Galecki tells TV Guide. "We're already tripping over bassinets onstage. That's enough."

Season 12 will premiere in the fall. It will air Thursdays at 8/7c for the whole season instead of starting the season on Mondays, since CBS no longer has Thursday Night Football getting in The Big Bang Theory's way.
