I have attached the notebook. It may be hard to read, but basically I am contemplating some sort of "universe change" which really alters c, G, h, or vacuum permittivity (the primed variables are post-change and the unprimed are pre-change) and then seeing how measurements change afterwards.
Thank you very much. This does look interesting, and I'll need some time to think deeply on this.
Just looking superficially, I'm intrigued by the fact that the measurement of speed seems unaffected provided that the product of fine structure constant and the gravitational coupling constant does not change. More specifically, speed measurement seems to scale inversely with the square root of the product of these dimensionless constants.
Based on this, would you say that this allows you to say to the OP that asking "why does light travel at the speed it does?" is equivalent to asking "why does the product of two dimensionless constants (which could be viewed as one effective dimensionless constant) have the value it does?"
In particular, why does [tex]{{1}\over{\sqrt{\alpha \; \alpha_G}}}\approx 2.8 \times 10^{23}[/tex] ?
