In Star Trek, why does Capt. Christopher lose his memory when the Enterprise beams him into his fighter jet?


In the Star Trek episode, "Tomorrow is Yesterday," the USS Enterprise is thrown back in time to the 20th Century of Earth. The crew saves the life of an Air Force pilot, Captain John Christopher, by beaming him aboard.


Fearing Christopher could disrupt the timeline if returned to Earth after glimpsing the future, Kirk decides Christopher must stay with the Enterprise. After Science Officer Spock later discovers that the pilot's own as-yet-unborn son will play an important role in a future space mission to Saturn, Kirk realizes he must return Christopher to Earth, but without any knowledge of Enterprise or other future events.


When the Enterprise moves forward in time again, it beams Christopher back into his F-104 fighter jet at the very instant after he was beamed off his jet. When Christopher returns to his fighter, he has no memory of being aboard the Enterprise.


Why does he have no memory of events aboard the Enterprise?


This seems like a plot hole to me. (Or a plot device made up by scriptwriters who didn't want an Air Force pilot knowing about the future.)



Answer



From the episode's script, it seems that the writers tried to address this problem, but their explanation is, in my opinion, very unsatisfactory:



CHRISTOPHER: Slingshot effects are fine for you people. How do you propose to return the Sergeant and me?



SPOCK: Logically, as we move faster and faster toward the sun, we'll begin to move backward in time. We'll actually go back beyond yesterday, beyond the point when we first appeared in the sky. Then, breaking free will shoot us forward in time, and we'll transport you back before any of this happened.


KIRK: You won't have anything to remember, because it never would have happened.



No, it doesn't make any sense. But that's the canon explanation: going back in time erased Christopher's memories of everything that happened since the point he was sent back to.


The only piece of in-universe explanation I can speculate on is this: since nobody onboard the Enterprise lost their memories, it must have had something to do with being beamed off of the ship while it was undergoing the slingshot. The transporter bypassed the ship's warp field's temporal normalization actuators, or something like that. Technobabble is the best answer I think we could expect in this instance.


Time travel in Star Trek is hopelessly inconsistent: exhibit A.

story identification - Animation: floating island, flying pests

At least 20 years ago I watched a short animated film which stuck in my mind. The whole thing was wordless, possibly European, and I'm pretty sure I didn't imagine it... It featured a flying island which was inhabited by some creatures who (in my memory) reminded me of the Moomins. The island was frequently bothered by large winged animals who swooped around, although I don't think they did any actual damage. At the end one of the moomin creatures suddenly gets a weird feeling, feels forced to climb to the top of the island and then plunges down a shaft right through the centre - only to emerge at the bottom as one of the flyers. Answer Skywhales from 1983. The story begins with a man warning the tribe of approaching skywhales. The drummers then warn everybody of the hunt as everyone get prepared to set "sail". Except one man is found in his home sleeping as the noise wake him up. He then gets ready and is about to take his weapon as he hesitates then decides ...

harry potter - Did Dolores Umbridge Have Any Association with Voldemort (or Death Eaters) before His Return?

I noticed that Dolores Umbridge was born during the first Wizarding War, so it's very likely she wasn't a Death Eater then (but she is pretty evil -- who knows?). After that Voldemort was not around in a way that could affect many people, and most wouldn't know he was planning to rise again. During that time, and up through Voldemort's return (in Goblet of Fire ), did Umbridge have any connection with the Death Eaters or with Voldemort? Was she doing what she did on her own, or was it because of an association with Voldemort or his allies? Answer Dolores Umbridge was definitely not a good person. However, as Sirius points out, "the world isn't split into good people and Death Eaters". Remember that he also says that he doesn't believe Umbridge to be a Death Eater, but that she's evil enough (or something like that). I think there are two strong reasons to believe that: Umbridge was proud to do everything according to the law, except when she trie...

tolkiens legendarium - Did Gandalf wear his Ring of Power throughout the trilogy?

After Gandalf discovered that Sauron was back and sent Frodo on his quest to Rivendell, did he continue to wear Narya (one of the Three Rings)? It seems like a huge risk to continue to wear it after the Nazgûl (Ringwraiths) started to try and reclaim the One Ring; if they managed to get the ring to Sauron, couldn't he be corrupted by his power? Whatever powers Narya bestows upon him couldn't possibly be worth the huge risk, could it? Answer When Sauron forged the one ring and put it on his finger, the other ring bearers were immediately aware of him and his intentions and removed their own rings. There is no reason why they couldn't merely do so again. As soon as Sauron set the One Ring upon his finger they were aware of him; and they knew him, and preceived that he would be master of them, and of all they wrought. Then in anger and fear they took off their rings. "Of the Rings of Power and the Third Age," Silmarillion
