  The distribution of spin direction of ~6.4*10^4 spiral galaxies with spectra
was examined. The analysis shows a statistically significant cosmological-scale
asymmetry between galaxies with opposite spin direction. The data also reveals
that the asymmetry changes with the direction of observation, and with the
redshift. The redshift dependence shows that the distribution of the spin
direction of galaxies becomes more homogeneous as the redshift gets higher. The
data also show photometric differences between galaxies with opposite spin
patterns. When normalizing the data by the redshift, the photometric asymmetry
is eliminated. However, when normalizing the data by the magnitude,
statistically significant differences in the redshift remain. These evidence
suggest a violation of the cosmological isotropy and homogeneity assumptions.
Fitting the distribution of the galaxy spin directions to a quadrupole
alignment provides fitness with statistical significance >5 sigma, which grows
to >8 sigma when just galaxies with $z>0.15$ are used. The data analysis
process is fully automatic, and it is based on deterministic and symmetric
algorithms with defined rules. It does not involve neither manual analysis of
the data that can lead to human perceptual bias, nor machine learning that can
capture human biases or other subtle differences that are difficult to identify
due to the complex and non-intuitive nature of machine learning processes.
