Over the last decade, new data from distant SN1a supernovas has cast doubt on the Hubble concept. At high Z, the observed distance exceeds that predicted by a linear Hubble plot. The main reason for curvature in the Hubble plot is the relativistic change of metric by gravity. Other corrections are needed, i.e. red shift to velocity and distances extrapolated to constant time. High Z SN1a's sent their messages long ago, when the big bang's gravitational potential was greater by a factor of up to 3. The relativistically shrunken metric increases the optical distance, much like an index of refraction. This makes them dimmer. The effect is like the Shapiro time delay. Relative to elsewhere, away from any gravity, our index of refraction n due to gravity is 2.75 at this time. At Z=1.2, n was 8.3. Parameters fitted to the data are A =2GM/c^2R_0=0.675, and R0 =18.4x10^9 light years, in our metric. The Hubble concept remains valid: recession velocity is proportional to geometric distance. There is no evidence for any slowing. The relativistic index of refraction is now greatest at the center of our big bang.
