I like the analogy...though after writing this rant, I must disagree. It brings to mind the basic concept of a shortcut, in which an object can maintain speed, and technically, direction (perhaps, more precisely, especially in regards to space/time, destination), while utilizing an alternate terrain, or in this case, space/time plane, aka, the Aether. Now, I propose, that unlike Agartha, the Aether is not necessarily an alternate dimension, but rather an alternate plane. We begin to get the picture if we envision real space/time as a coil (which would better explain the rotating teleporter graphics and the electrical properties of a teleporter-I like how spellcheck doesn't recognize teleporter"), so yes, a coil, with this plane "the Aether" acting as a rotating axis, perhaps powering or "gravitating" space/time in this pattern like an electromagnetic pole.
This theory neither breaks down cell structures, destroys or creates matter, yet maintains the teleported object's velocity without annihilating the object due to it exceeding the speed of light, one of these processes Maxis may have been attempting, as his attempts at teleportation were so far behind Richtofen's, who realized the concept of the Aether.
As a note, I will argue against retrospective time travel. As someone on this forum once observed, (I would credit, but I don't recall-it may have been MysteryMachineX-the fullest extent of retrospective time travel is limited to the first use of said time travel, as a "timestamp" if you will, not unlike the time bomb from buried.
