Everything must come to an end, but for “The Big Bang Theory” fans, this may be the most tragic thing that could happen.

Showrunner Steve Molaro hinted, in an interview with The Hollywood Reporter, that season 10 may be the last for the CBS hit comedy series.

The Big Bang Theory” is currently in its ninth season and has been renewed until 2017.

Speaking about the series, Molaro said: “I can’t speak to the future or on behalf of the cast or where we’ll be then but it’s certainly possible that it could go past that. The reality is that maybe season 10 is the ending point. The real answer is I don’t know and all I can do right now is go episode to episode and try to make each one the best that we can. There’s still so many episodes to go.”

“Even if hypothetically season 10 was the end, I wouldn’t be focusing on that yet. That seems like something that would be dealt with way down the line,” he added.

Co-creator Chuck Lorre, on the other hand, said he doesn’t want to presume how many years the show will run.

“It’s already gone beyond my wildest dreams so anything beyond this…as long as everybody is having a good time and we’re making a show we’re proud of…then it’s worth continuing,” Us Weekly quoted Lorre saying.

Meanwhile, Molano also hinted that new storyline and characters may come up in the show.

“There are still a lot of characters out there in this world that we’ve never met that I’m still excited, over the next season and a half, to get a chance to do something about. We’ve never met Penny’s mom, Leonard’s dad, Sheldon’s Meemaw or Howard’s dad — and that’s a big tentpole that’s still floating out there,” said Molano.

Last week, two of the major characters of the show – Sheldon (Jim Parsons) and Amy (Mayim Bialik) – made a major leap in their relationship. The super-nerd professor chose to have sex with Amy instead of going to the premiere of his favorite movie of all time “Star Wars”.

“The Big Bang Theory” returns to CBS on January 7, 2016.
