It would be less that time moves faster on one side or the other, and more just a relationship between when you entered on one side, and when you exited on the other. Say for example, entering at time x on one side, would always result in ending up at time y on the other side, and entering at time x+1, would have you exiting at y+10. In that case, it's not so much that time is moving faster or slower on one side, rather, it's a function of when a portal leads to, dependent on when you enter. And the portal on the other side could have the inverse. I mean, I suppose it doesn't have to have the inverse, but if it didn't, then you'd end up with the problem that moving through the portal one way, and immediately going back through the other way, could have you end up some time forward, or backward, of when you first entered.
Alright, so for the sake of locality, and energy conservation, there has to be a forward, one-to-one mapping. I suppose that is reasonable. But Planck's constant (And consequentially Planck length, and therefore Planck time) must be very short indeed over there. And that has some interesting repercussions for quantum mechanics in Narnia... One must wonder if the human body, or even particles from our physical system, could even coexist with Narnia particles.

And who knows how invasive an inter-dimensional portal actually is? I mean, if this is something that can move objects between different timelines, then using a workspace timeline, it could literally have all the time in the world to disassemble, reassemble, repair, record, etc., whatever it sends through, and make it appear seamless. And no matter how long or short such a thing would take, whatever is passing through could end up at the same time on the other side, and in the same state.
But could you cram 25 years of adult learning into a child's brain? Seems like the brain mapping would have to take hormonal changes into account — the end results of which might be sloppy. Also, if timelines must be matched 1-to-1, then in order to have infinite time, the workspace timeline needs to be a real universe with infinite negative entropy to fuel limitless operations on travelers...
Soralin wrote:Depends on how it works, it would definitely have to get the energy from somewhere. If that had to come entirely from the kinetic energy of what's entering, then it would be really hard to get most objects through. The two sides would have to be at practically equal elevation.
Not necessarily elevation, but equal gravitational force. Some of the constants are likely different in Narnia, but as long as acceleration "g" is the same at their exit as it is at the location of the wardrobe, no additional energy is needed.
Soralin wrote: I mean, if the gravity is the same, and if there's even 10m difference in elevation, an object would have to be moving through it at at least the same speed as it would take to launch something 10m skyward here on Earth.
Of course, if the workspace can assemble anything into any state, it can just move objects between gravitational potential energies at will, without conscious observers even able to notice a seam.

It would also mean that could could effectively disable the connection, or make it rather deadly, by moving one end up a couple stories in a building, or any other change in elevation, or from minor differences in local gravity.
On the other hand, if it's drawing power from some other source that shouldn't be a problem, and if you have a device that can connect universes, you have a lot of power options available to you, like setting up a connection to the inside of a star.
Well, I suppose that could provide a very significant amount of free energy for any device capable of linking universes. But why this machine, which we have determined must be capable of incredible and intelligent function, would allow large amounts of salt water to pass through, goes without explanation...

If you listen to the developer commentary, play around in the game yourself,and view videos like the one below, you'll know that the physics in Portal
is not really good canon for how portals should behave. http://www.youtube.com/watch?v=cxFrifq6rsI
I can't go, this is too important. Someone is wrong on the internet!
