Addendum: If L was imaginary, that means motion of the light clock, and consequently its observer, in an imaginary direction. What could that mean? Perhaps a fourth spatial dimension? Of course, you'd have to go forth and back between the fourth dimension and our third otherwise I suppose you'd be trapped forever in some higher dimensional plane and that doesn't sound pleasant. How would that work? It's quite convoluted. I'll try to draw it, beginning with a four-dimensional space-time graph (or at least my best attempt at it). The real issue with people when they try to make things 4-dimensionally is that they concern over continuity. At integer-time intervals like what I'm making, it becomes simple, I guess. The spacetime diagram gives the relevant details for 3-dimensional space plus a time dimension. For simplicity, assume that each progressing XYZ-axis to the right signifies an advance in the time dimension by one tick (or whatever they...
Logically, time cannot pause completely. But how about, we slow it down? Friendly note, don't take this seriously. I'm not qualified for hoc stercore . Similar to how Einstein worked out time dilation with light clocks and the postulate that light always travels at a consistent speed c , perhaps we can use light to create a scenario in which time seemingly has that the clock of the observer apparently speed up with respect to observers. Say there are clocks A and B and there are observers there, observers A and B. The goal of the scenario is to have A appear faster than B to B. I'm making this up as I go along. Let's set up some limitations. In B's perspective, A must never appear to be faster than light. Violates relativity (especially in the sense that would require infinite energy plus some more and we can't get infinite energy since infinity itself isn't a value per se, but rather a door you can't ever get to). Another one, energy canno...
