Not sure I understood everything you were talking about there, again, using the terminology that I am not fully educated in is only adding to the confusion.
I'm trying to avoid being too snarky, but there is plenty of information publicly available on the Internet to help you familiarize yourself with basic concepts of relativity and, most importantly for our discussion, the concept of frames of reference and the fact that there is no preferred frame.
I understand that anything going over a distance is travel, but what distance is traveled between the wormhole sides? It's a 2 dimensional space, right?
No, I'm not sure why you would think this.
Take a balloon, pinch part of it together, poke a whole in the middle and seal the edges of the hole. The entire surface, including the 'wormhole', is two-dimensional. Scale this up a dimension, and the wormhole gains one too. The wormhole still has 'depth'.
However, it isn't remotely necessary for our discussion to be at all concerned with that. An ansible or other instant teleport device or reducing the wormhole to such is not necessary, it's just convenient, because it's where math as in the above is the most accurate.
Someone walking at say, 2mph going into one side is walking the same 2mph coming out the other and if those ends of the wormhole are at opposite sides of the universe, does that mean that they have said ungodly high speed of some FTL travel, or were they only going at 2mph at all points?
It means they have violated the dominant energy condition. It's not generally appropriate to consider any sort of remotely physical (and physicists will probably poke at me for that, but whatever) faster-than-light travel to have 'a speed'. How fast something moves FTL is going to depend on the frame of reference of whomever is observing it. It is, in fact, possible for many FTL mechanisms to appear as slower than light in some suitably absurd frame of reference. Star Trek is the most typical example.
It's well known that there are galaxies out there that are traveling away from us at speeds greater than the speed of light. It's not due to said galaxy actually traveling faster than the speed of light,
but due to our mutual speeds traveling away from a random set neutral point between our two galaxies and the expansion of the universe.
The former is meaningless. The latter is correct.
At no point is any going FTL,
but combine all the factors and FTL is observed.
Incorrect. The expansion of spacetime across the Universe creates a horizon, past which we cannot observe. Therefore, while we are well aware
of this phenomenon, the actual observation is not possible - the FTL is created because of the deformation of spacetime itself, and galaxies past this horizon cannot send a photon to reach us, thus preventing our observation.
I don't like saying it this way, but it's one of the better ways of putting, all speed is relative. Two ships traveling in the same direction next to each other at the speed of light, relative to each other neither is traveling but you put them heading opposite directions and they are now traveling at twice the speed of light... relative to each other.
Incorrect. A ship moving at the speed of light would presumably have an infinite horizon, but if you have two ships at rest, and each moves in opposite directions away from each other at .9999 of c, they will each observe the other ship receding from them at a rate defined by the relativistic velocity addition formula
(.9999 + .9999) / (1 + .9999^2) = 0.999999995
In order for the relative speed between them to actually exceed the speed of light, the expansion of space between them needs to be what pushes them over the edge. Much easier to just drop one into a black hole, but the finality of that might disturb the occupants of said ship.
Back to the wormhole on the Earth/ship reference. Again, if I am understanding what you are saying, when someone looks into either side of the wormhole, either from the ship or from Earth, everything appears slowed down. Again, that is if I am understanding what you are saying.
While the faces of the wormhole have a relativistic speed difference, yes.
But, there is no FTL travel, or even any travel beyond what travel could be hand when looking from one room into another through a door frame. But, that is only if what I understand of wormholes to be correct and they are (put simply) just two sides of a 2 dimensional surface.
We could pretend such a wormhole existed as a thought experiment, but it wouldn't change the reality that travel occurs.
I have an idea, instead of replying back to this whole post, lets start from fresh.
A wormhole, is it just two sides of a two dimensional space where traveling between the two puts you from one point to the other by just taking a step through the opening? Where there is actually no space between the sides so no travel is had from entering to exiting. If there is a distance between the two sides, then how far is it? Does the distance between the containers of the openings affect the distance had between the entrance and exit?
I think you're confused.
You're declaring that it isn't travel by some sort of authorial fiat, like declaring pi to be 4.5 or the Sun to be a giant orange. Mass-energy has vanished from one part of the universe and appeared 100 light-years away. The distance is certainly much shorter in a very localized context, but a distant observer is still going to see a hundred light-years of near-instantaneous travel, and is going to have difficulty ordering the events on either side of the wormhole. That travel - regardless of the mechanism - still occurs.
