Constants and multiverse possibilities

[Chalnoth]

To my understanding any particle which has no mass requires no medium to propagate, but will propagate through a medium dependent upon its refractive index.

Not quite. The refractive index is a purely electromagnetic phenomenon, resulting from how charged particles respond to the incoming electromagnetic wave. So, for example, massive particles can move faster through a medium with some refractive index than light. For charged particles, this causes Cherenkov Radiation.

Thanks for clearing me up. I was just directed to that experiment by frame dragger and I omitted it accidently. Oops. It's a very interesting experiment by the way.

Spacetime has properties called permeability and permissivity. That is what imposes the speed limit on photons. This is a good thing. It prevents everything from happening all at once in the universe. If you are looking for deeper meaning in physics, that is a good place to start.

Well, it's not those two quantities themselves, but rather the relationship between them that sets the speed. And it's just a dimensional consideration: the speed of light is what relates the strength of the electric force to the strength of the magnetic force.

One of the problems of an intelligent universe is communication. The universe has to communicate with itself at a faster rate then the speed of light. I proposed in a previous post that quantum entanglement might do the job. What I gather from peoples post is that quantum entanglement can not be used to communicate, further all events can not be perceived to happen at the same time. If some sort of intelligence exists and is aware of cosmic events then there must be a way that events be dimensionaly stamped (four dimensions) and perceived at a faster speed then the speed of light. Since we haven't discovered a speed that's faster than the speed of light I conclude that there isn't an intelligent entity in control.

I think that's a very reasonable analysis.
