♈ Aradia: Explain the time travel in a hundred words or less! GO! [video]

[It's getting to be nighttime when Aradia films this. She's sitting on a sofa a little ways back from the camera, with a small stack of papers on the coffee table in front of her, and waves once she's sure it's recording.]

Hello, everybody. My name is Aradia Megido, Maid of Time. As you might guess from my title I have a great deal of experience with time travel. But while I have been here I've noticed a major flaw in the Initiative's overall plan; namely, that they don't seem to have any idea how time travel works.

[She reaches over and picks up the first paper, showing it to the camera:]

As you can see, the basic idea is that, by traveling back in time and altering certain events, we can sabotage the United Earth and improve our situation in the present.

[She pulls up a second diagram, holding the two side by side:]

crayon diagram of an immutable (splitting) timeline


In reality it is a little more complicated than that. Let's say, here, that the red timeline is one in which the desired result is achieved, whether that's the United Earth losing power or never achieving dominance in the first place, whatever. We'll call this "Timeline Alpha". The blue timeline is ours, in which a result occurs which we want to prevent. Let's say, the UE dominating the planet and everybody else dying.

As you can see, the time traveler does change the targeted key event. However, all this does is link two separate timelines, contingent upon how that event happened. Timeline Alpha continues with the alteration in place, but the offshoot timeline that caused the alteration continues without it. Because obviously, if no timeline existed where the event needed to be changed, no one would have gone back in time to change it.

[She puts down those two and picks up a third diagram instead:]

This leads us to the fundamental paradox of time travel, which is: the alpha timeline simultaneously must be changed, and cannot be changed. It is the final result when all temporal meddling is taken into account, as well as the only viable version of the timeline. All alternate timelines are, by their nature, doomed. Think of it as paradox space's way of cleaning up before things get too messy.

[Switching pictures again!]

Of course, you can travel within the alpha timeline as well, but only within the context of stable time loops. That's where you cause an event to play out in the way it already did. This is the only way you can affect the past without creating a doomed timeline.

That leads me to the first point I wanted to make - I don't think I'll have time to make the second, since the timer is coming up on five minutes already and I do want people to actually watch this.

[She picks up the first image again, holding it next to the fourth.]

Basically, either A) our time travel missions are having or will have a tangible effect on the alpha timeline, but our timeline is a doomed offshoot and will die off sooner or later; or B) this is the alpha timeline, but our intervention is and will be the direct cause of the current circumstances.

[PHEW. That was way more than a hundred words! She puts down both pictures and folds her hands neatly in her lap.]

I think that explains it adequately. Let me know if you have any questions, I will do my best to answer them. Thank you for your time! [PUN VERY INTENDED 0u0]

THAT'S COOL

So, it could happen at any time?

[ THAT'S REASSURING ]

Yeth.

And it'th not like what you're probably thinking of. It's not like a sudden apocalyptic thing. It's more depressing than that. It starts with unfortunate circumstances happening, and then gradually becomes a hopeless situation that no one could stop. Like for instance, if first, the machines that revived us stopped working. And missions kept coming in, and people continued to die for this cause, only for us to eventually realize that there's no point, and our attempts are futile.

I don't know much about time travel [ because it's important to begin with that ] but if that started happening, couldn't it be possible to go back and not end up affecting the thing in the first place?

[ or is a paradox of a paradox ]

What, you mean like. Person B goes back to change Person A's future, but Person C steps in the prevent Person B from doing anything at all?

[personal profile] argentite 2013-08-18 07:59 pm (UTC)(link)
Something like that, yeah. Could it work?

[personal profile] biwinning 2013-08-19 01:10 am (UTC)(link)
No. The timestream has still been altered, even if no severe action has been changed. It's like, say while Person C is there stopping Person B, and something breaks or someone is hurt. It still changes the timeline that happens in which no one goes back at all.

So, we're doomed either way? [ great ]

Why hasn't anyone taken this up with the people doing all the time travelling?
biwinning: (ii aiin't even mad.)

[personal profile] biwinning 2013-08-21 09:57 pm (UTC)(link)
I'm not an expert. So I didn't. But I'm sure Aradia could talk to them.

[personal profile] argentite 2013-08-22 02:52 am (UTC)(link)
I hope she does. [ pause ] Are you two related?

[ grey... skin... and all...... ]

We're both trolls from Alternia, if that'th what you mean.

[personal profile] argentite 2013-08-24 07:33 pm (UTC)(link)
I — uh, yes.

Trolls?
biwinning: (I've been a veteran of the unspeakable.)

[personal profile] biwinning 2013-08-24 07:40 pm (UTC)(link)
Trolls. From Alternia. Another planet. Not Earth.

Right, right, okay. [ aliens also exist. better remember that ] And she's Aradia and you're—?
biwinning: (Everything. Next question.)

Thollux.

[ she replays it again just for her own clarity because it — well it sounds an awful like a lisp but she can't be sure ]

So, Thollux?
biwinning: (pic#6507957)

[personal profile] biwinning 2013-09-03 11:32 pm (UTC)(link)
...

What the fuck do you think "with an eth" means?

You're not from Earth! Maybe there's a different way of saying things. How was I meant to know?

[personal profile] biwinning 2013-09-04 05:18 am (UTC)(link)
I TOLD YOU HOW TO THAY IT! I thaid "with an eth!!"

HOW DID THIS TURN AROUND SO QUICK

[personal profile] argentite 2013-09-04 05:27 am (UTC)(link)
Eth isn't a real thing, unless you mean "ess".
biwinning: (Celebrate this movement.)

You could've just said that from the start.
