Firstly it admits once again that despite people keep saying:
Despite the predominance of the current redshift paradigm, little direct observational evidence exists in support of cosmological expansion.
Secondly, it tells us that in measuring “time dilation” some of the techniques used in the past assumed a 1 + z dilation in the first place – and then told us that the results showed time dilation existed!
Thirdly, it tells us that an expanding universe predicts the wrong results.
Stationary Sn Ia’s have spectral features separated by 17 and 18 days.
The BB predicted 18 and 23 days.
In actuality the measured separations where 25 and 31 days.
