“SHELDON BECOMES A SUPERVILLAIN… KIND OF”
One theory claims Sheldon will suffer a post-Nobel ego spike so massive that he becomes the scientific equivalent of a comic-book antagonist.
Evidence fans cite:
-
His lifelong desire for “absolute intellectual order”
-
His history of escalating petty rivalries
-
A leaked image of a costume-looking lab coat

The theory ends with Sheldon delivering a dramatic monologue about reorganizing the entire physics department by IQ ranking.
Fans love it.
Amy would hate it.
Therefore it might happen.
“RAJ FINALLY GETS A GIRLFRIEND… AND SHE’S FROM THE FUTURE”
This one is pure chaos.
Fans believe Raj will date a woman who claims she’s from the future — but the twist is that only Sheldon believes her.
Supporting evidence:
-
Raj’s history with fantastical romantic delusions
-
A rumored prop labeled “TEMPORAL DEVICE – DO NOT KNOCK OVER”
-
A behind-the-scenes photo of a futuristic wristband
This storyline would let the show parody Interstellar and Arrival in one go.
And honestly? It sounds on brand.
“PENNY IS SECRETLY WRITING A BOOK ABOUT THE GROUP”
Some fans speculate the revival will reveal Penny has been secretly documenting the group for years to pitch a memoir titled:
“Living With Genius (And Leonard).”
The theory exploded after Kaley Cuoco joked in an interview:
“Penny would totally profit off the group. In a loving way.”
Fans think the season finale will be Penny reading the final chapter…
…which fades into the show’s opening scene.
Full circle.
