This thing all things devours

I'm in the middle of a horribly tedious rewrite and have had a crushing thought: I don't think my definition of time jives with my meaning of light being "instantaneous". Again I get that feeling that everything I'm talking about is exactly the same as what's been known for the last 100 years, and anything different is nothing more than poor wording.

I've been completely wrong in the science, the math, the language. The only thing that endures is the idea. Will it be boiled down until it's nothing more than a repetition of what I've read? Or will it be polished till it gleams, like a beautiful delicate golden turd?

Yet more contemplation and rewriting.

If time is distance, then a moment in time with 0 duration is a single point. That is not light.

If light is not a moving thing, then what is it? It is not a single instant, because it spans time (distance). Yet it is at all points along that distance simul... simul-what? It spans time but it does not move through time. Does it bridge time? No, it does only exist at a single time value, but that time value is different for different observers. And does it not actually exist as a line of energy, observable along its entire length as single points of light by different observers, but rather exists only at its source and its destination? One cannot "see" a light signal unless it is intercepted, and though you can intercept signals all along light's path if there are enough signals (like a laser through a smokey room), it is still only observable at source (as a loss of energy) and destination (as a gain).

Perhaps then light is simply a teleportation of energy. It slips out of existence in one observation-defined location (and time), and shows up elsewhere. Yet, the path is important because it determines where the destination will be. Energy teleportation makes sense within the idea of a singularity, but how is geometry and the difference between matter and space represented within a singularity? And is the singularity idea really needed, when there is no way to observe a light transmission occurring in a single instant?

Or something.
