CBS has just released a couple of fall teasers for its returning series during the Television Critics Association summer press tour, and it included one of "The Big Bang Theory."

Given the amount of hype and endless talks fans made about the upcoming season, the teaser isn't really much of a teaser, but at least fans finally have a clue now what is really going on inside the heads of their favorite characters, according to TV Line.

The teaser for the first episode of "The Big Bang Theory" reads: "Brilliant Sheldon is confronted by a mystery of the universe he cannot unravel: when a woman wants time apart to think, exactly how much time does that mean, and is there any way to hurry the process along? In Las Vegas, Penny and Leonard march closer to marching down the aisle, but has Penny gotten over Leonard's infidelity? And if so, will he do anything to un-get her over it?"

Knowing Sheldon, he will bug Amy or his friends relentlessly for an answer to his question. As for Leonard and Penny, introducing the girl he kissed behind Penny's back would surely create a lot of awkward tension between the couple that would give fans a lot of good laughs.

Mayim Bialik, the actress who plays Amy Farrah Fowler in the series shared some set photos with her co-star Jim Parsons, the actor who plays Sheldon, so fans already know that their characters will still be interacting with each other in the upcoming season.

As for the mystery behind Sheldon's ring, Bialik told fans not to jump to conclusions, and during an interview with the Los Angeles Times, she said, "We don't really know what the story is with that ring."

"And I think that's something I had to remember as an actor. We don't know what he was planning to do with it. We don't know if it was something he got from his mother. We don't know what the process was by which he acquired that and what he would think to do with it," she added.

The teaser did not say anything about the rest of the gang - Howard, Raj, and Bernadette. Would Howard and Bernadette finally find the right scenario and words to get Stuart out of their house, or will the comic book owner be a permanent fixture in their household?

As for Raj, will he muster up enough courage to finally break up with his girlfriend Emily, or will he let the relationship continue? Should they break up, will Raj find love elsewhere or will he be happy being the only single person in their group?
