Hi! I'm interested in alternative cosmologies and the variable mass hypothesis developed by arp and narlikar seems to explain better the discordant redshifts: but I can't understand how this theory calculates cosmic distances according redshift and time. Narlikar says that " We have here a flat spacetime cosmology in which light waves travel without spectral shift. How then do we explain redshift ? Consider a galaxy G at a given radial coordinate R, the observer being at R=0. A light ray leaving the galaxy at T0-R/C reaches the observer at time T0. Since the masses of all subatomic particles scale as T^2, the emitted wavelenghts go as m^-1 & t^-2.Hence we get the factor:

1+Z=

T0^2

__________

(T0-R/C)^2

I don't understand....if a galaxy has a redshift z=6.5 for exemple, how distant from us is it ?

There is somebody well up in these things ?? Thank you....
