Tomorrow is Yesterday ...WTF?

How are the probabilities determined then? What makes one state more probable than another? And another, and another...
 
It's not so much a matter of probability as preponderance. Quantum particles are influenced by the particles they interact with, and an entity that's part of a larger quantum state, e.g. a timeline, will be "in sync" with that state. Think of it as "going native."

Of course, by this logic, any character who traveled to an alternate timeline and met her duplicate self would instantly be subsumed into that other self. But we can assume that it's some particular quirk of the transporter beam that allows the coalescence, since a body in transporter transit is kind of in flux quantum-mechanically speaking.
 
I don't have a problem with ordinary matter finding its way like that; but I don't expect Spock to be able to find a different time line and beam somebody into it. That's the real problem.
 
He didn't "find" the timeline. When the Enterprise doubled back on its own history, it basically erased itself from the timestream -- in my quantum model, the two iterations of the ship converged into one, and the later one took precedence. Though admittedly that contradicts having the earlier/"local" versions of Christopher and the Air Force sergeant take precedence in those mergers. Maybe it's because the Enterprise, and the versions of those people affected by it, didn't "belong" in that place and time and so, of the two quantum states, the "default" one took priority.

Look, ultimately it's never going to make sense. It was a plot device, and any explanation other than "it's in the script" is heavily leavened with handwavium.
 
Indeed. Which is why I didn't introduce any other thing back up there in my first comment. I was going along with it. I'm more than happy to use this episode without knowing how it works. But, no; you had to contradict me. :lol: That is red-flag wavium. That bit about getting time-travel out of doubling back on itself is a real ugly thing.
 
Thanks folks for all your replies and explanations. It hasnt cleared it all up in my head but it does make me feel better knowing i didnt miss something that everyone else understands or at least agrees upon!

My recommendation - if it hurts your head to think about it, ignore it and just go with the flow. Don't worry, be happy.

I find it allows me to enjoy this episode much more.
 
I've searched thru the threads and didnt find any addressing this question (but if i've missed one, please forgive me)...

i just finished re-watching Tomorrow is Yesterday and was left with a big WTF? Is it just me, or did the whole 'go back in time and re-transport Cpt Christopher and that dopey security guy' NOT MAKE SENSE?

Can anyone explain to me how they returned those guys and how the people they beamed back suddenly forgot what happened to them?

Or was that all just one big 'whoops' as far as common sense goes?

Thanks in advance. And, if i am showing my stupidity please be kind.

What's more - did each of them gain DOUBLE their original body mass? (As to it not making sense, I do agree, but what's Star Trek without a good McGuffin ending at times?) ;)

And it is an enjoyable episode. I like Captain Christopher; and I think viewers identify with him and find his reactions -- and those of the Enterprise crew -- interesting and fun.

"If that thing starts up, it will make the devil's own noise!" -- Sulu :lol:

It's the rule of Camp and Fun, just have a good laugh and let it be.

Oh, i did. It WAS a fun ep thats for sure. That dopey security guy and all. But theres that little part of me that always wants it all to make sense.

Anyway, thanks all for helping me on this one!
 
Except for the tiny detail that Christopher's plane disintegrated a second later. Oops!
In fact, it doesn't, you might notice. They figured out NOT to put the tractor beam on it again from the first occasion.

No, the idea was that this was a timeline in which the Enterprise wasn't present at all.

I like to look at it as a quantum-mechanical thing. "Parallel timelines" are really different quantum states of the universe. So the you in this timeline and the you in a parallel timeline are actually the same entity made of the same particles; that ensemble of particles is simply existing in multiple collective quantum states. So the Christopher that was beamed off the Enterprise and the Christopher in the jet plane in another timeline were actually a single entity all along, and beaming them together basically just caused the two quantum states to collapse back into one, a single person with a single set of memories -- the memories consistent with the quantum state of the larger reality he occupied, one in which the Enterprise wasn't present.

Bravo! Posts like this are what keep me coming back here.
 
Kirk told Christopher "You won't remember anything because it will never have happened." By the same logic, the Enterprise crew shouldn't remember anything about the adventure when they return to their own century.
 
Perhaps they wouldn't have had they beamed themselves into themselves at the moment they broke away from the black star. :)
 
This worked the same way they stitched Kirk back together in "The Enemy Within".

Deus Ex Transporter e.g. the Transporter fixes everything.
 
Folks, they just hit the "reset button" and everything's OK!!

Holy crap...could this be the first use of the Reset Button in Trek lore? :eek:

Ah yes, the oft-maligned "reset button." Which of course is a derogative term for episodic television (which was of course, the absolute standard for series TV when TOS was conceived, written and aired). I submit to you that without it in TOS, there would be no Trek today. Nor could there have been. (Episodic TV was a requirement for syndication then... not to mention the 70's public would not have watched a story-arced series that was rebroadcast out of order-as it most definitely still would have been.)
 
EEE is correct that "reset button" could be said to be THE model for most episodic TV, as you have to leave the characters where they were at the start in order to keep the show the same and static. On the other hand, I always presume "reset button" to be a show where something huge happens that will change the world or one of the characters, and some plot device is used to "undo" it, as if it never happened.
 
As I always say............

"Even when i was a kid........." I didn't know how any of the end of that episode could make any sense. I just figured i'd understand the tech when i got older.

Not old enough yet............
