I apologize, I forgot to look up that paper, which I believe has the intensity formula in it. I will do this tonight. I don't think it is more complex than: I_1 / I_2 = (R_2 / R_1)^2 ... using a "standard candle" for I_1 and R_1, measuring I_2, and solving for R_2. Some "standard candles": http://csep10.phys.utk.edu/astr162/lect/cosmology/cosmicd.html (which you proabably already know) > >> Time dilation applied to the decay curve is some > >> part of the analysis, but that calculation implies > >> recession velocity, not a/a0.

Otherwise we'd have to make up special rules for places we cannot see, and we have no basis upon which to do that.

Additional space equates to additional states, something that SLT does not allow reduction in. > not excepting the unblushing use of dark energy I agree here. How is "energy" necessary if gravitation is not a "force"? But like the "Big Bang" and "E=mc^2" for even motion energies, things tend to stick. > and quintessence and matter/radiation percentages. > Still can't find the z/distance transform.

We can't believe it is that "hard" or that "odd" or even that "marvelous". David A. Smith
