A new study by Riess et al seems to have confirmed that something, once again, is wrong with the BBT model.

Part of the problem lies with the earlier mistake made by him and others in their nobel prize winning paper of 1998. They realised back then that the lightcurves of distant SN1a were too “dim” to be explained by the BBT. So to get around this massive failure of their BBT model they added another pre-copernican fix to their preferred model of expansion. And called this fix ‘acceleration’.
What they failed to take into account is the fact that a non expanding model of the universe predicts that these distant SN1a will not have *time dilated* afterglow lightcurves. And thus the SN1a afterglow is predicted to appear to be fainter post peak fluence in a non expanding model than is predicted in an expanding model.
And...this is exactly what is observed in Riess et al’s 1998 data. Far from confirming the BBT with an added fix of acceleration, what they actually did was confirm the non expanding models predictions and proved that the universe isn’t expanding at all.
And so now this failure to understand the data by Big Bang theorists in 1998 has come home to haunt them again. Riess has just confirmed once again that the BBT is a failed model. And that once again Riess’s data shows the universe isn’t expanding. Except this time he can’t think of an easy excuse. Although its apparent he still doesn’t blame the BBT model. And instead says that somehow there must be new physics. New fantasies to cover up old fantasies failures is what he really means.
It is worth pointing out here the oft repeated claim made by BBT supporters that SN1a lightcurves show time dilation and confirm the BBT model. When using chi^2 fitting methods to match observed SN1a data to theoretical time dilated templates . Knop et al 2003 being one example.

This claim is dubious at best. Because analysis like this fails to do a control test on the SN1a data to see if a chi ^2 match to *non dilated* lightcurve templates can give as good, or even a better match to that of time dilated templates.
And I have shown quite clearly in my blog page on supernova-light-curves-fit-non.html that yes in fact the same hi-red shifted SN1a data gives at least as good a match to non dilated templates as it does to BBT inspired theoretical time dilated lightcurves. If not better. Considering that to make the SN1a data fit the dilated lightcurve templates, Knop had to arbitrarily fiddle the individual Hubble Space Telescope datapoints by as much as 15 % in luminosity to make a good fit to the expanding BBT models theoretical lightcurve templates.
