Raj, Sheldon, Leonard, and Howard cosplay as Worf, Data, Picard, and a Borg in Season 6's "The Bakersfield Expedition"

The Big Bang Theory is a CBS (current owner of the Star Trek franchise) sitcom about four science nerds and the hot girl who lives across the hallway. The four scientists are rabid science fiction fans and collectors of memorabilia thereof, Star Trek in particular, resulting in the show featuring a constant flow of Star Trek references in the vast majority of the show's episodes. The show features Brian George and Keith Carradine as Raj's and Penny's fathers, Pasha Lychnikoff as a cosmonaut on the International Space Station, and Mark Harelik as the CalTech physics department chairman Gablehauser. Star Trek actors Wil Wheaton, Leonard Nimoy, George Takei, LeVar Burton, and Brent Spiner have all made appearances on the show, as fictionalized versions of themselves. Cast member Kaley Cuoco also played William Shatner's daughter in commercials, and Iris Bahr had appeared in the original unaired pilot for the show.

"The Bat Jar Conjecture"Edit

The episode begins with Howard announcing new info on the then-upcoming Star Trek film, which leads into a discussion about alien private parts and Spock's conception. Later Sheldon is persuaded to join in the Physics Bowl by quoting Spock's dying words. Sheldon makes up TOS uniform-style shirts for his Physics Bowl team, with his teammates as redshirts. Ultimately in the final scene, to satisfy who is smarter between Leonard and Sheldon, Penny asks multiple real-world questions for which they are only able to give Star Trek-like answers, including Patrick Stewart or William Shatner being the Sexiest Man Alive and Tweety Bird thinking he saw a Romulan.

"The Nerdvana Annihilation"Edit

The guys purchase a time machine prop from the movie The Time Machine and they decide to play with it. They wonder what time date to travel to and Sheldon suggests to Leonard that he should travel to the future to obtain a cloaking device and references "The Enterprise Incident". Sheldon gives the stardate of this episode as 5027.3, which supposedly converts to January 10th, 2328. The stardate is correct, but traditionally the episode is placed in 2268.

"The Lizard-Spock Expansion"Edit

Sheldon expands the game of Rock-Paper-Scissors with additional options of "Lizard" and "Spock," the latter symbolized by the Vulcan live-long-and-prosper hand gesture. It was used initially to determine whether or not to watch Star Trek: Deep Space Nine.

"The Creepy Candy Coating Correlation"Edit

"The Thespian Catalyst"Edit

Sheldon and Penny act out a fan fiction story he'd written as a child where he's whisked away to the 23rd century, with Penny playing Spock. She perfectly executes the hand salute at one point.

Wil gives Sheldon an autographed still-in-package Playmates Toys Wesley action figure, but Brent Spiner promptly opens it upon seeing it. Brent then offered Sheldon a autographed still-in-package Data action figure to make up for it, but Sheldon declines and declares Brent his new mortal enemy.

In the background at the party are Star Trek writers D.C. Fontana and David Gerrold. They can be seen talking with Kevin Sussman, who plays the show's character Stuart Bloom, who owns a comic book store the main members of the cast frequent.

"Spock toy" enticing Sheldon to play with his transporter toy

Penny bought Sheldon and Leonard a mint-in-box 1975 Star Trek transporter toy each. However, they refused to play with them as the toys would lose some of their perceived value within toy collector circles. That night, Sheldon dreamed that his Mr. Spock action figure (voiced by Leonard Nimoy) told him that it was illogical to own a toy that he wouldn't play with. Shortly afterwards, Sheldon accidentally broke his transporter while playing with it and then replaced it with Leonard's. Later, he had a nightmare about being chastised by Mr. Spock about his actions and was subsequently attacked by a Gorn. Appropriately chastened, Sheldon confessed his guilt to his roommate.

Season 9Edit

"The Spock Resonance"Edit

Wil Wheaton and Adam Nimoy come over to interview Sheldon for Adam's documentary about Leonard Nimoy.
