Accelerated expansion and lightcurves

  1. Jun 26, 2010 #1
    Is the time dilation associated to cosmological redshift that can be seen as a photometric slowing of the SNe Ia lightcurves directly related to the accelerated expansion seen on these same type of supernova from 1998? If not, what's the difference?

    nobody here heard of the time dilation test? or lightcurves?

    What time dilation are you referring to , I know they tested the gravitational red-shift of light , with the pound-Rebka experiment and verified gravitational time dilation
