  I further test the theory that the Cosmic Background Radiation (CBR) is made
of photons with a weak U(1) component. Tipler (2005) has previously argued that
the consistency of the Standard Model (SM) with the Second Law of
Thermodynamics requires the early universe CBR to be composed mainly of an
SU(2) gauge field. The U(1) field would be suppressed. One of the consequences
of this approach is that the Ultra High Energy Cosmic Rays (UHECR) would be
able to propagate much further than conventionally accepted, as an SU(2)
dominant CBR would be largely unable to couple with right handed fermions. I
test if this novel theory solves the problem of UHECR origin by finding
suitable candidates up to a redshift z = 0.1 within three degrees of the
arrival direction. Utilizing the Fly's Eye Northern Hemisphere UHECR data, I
identified candidates with 80\% success for the Northern Sky UHECR (98.7\% if
certain celestial objects which are likely to be Active Galactic Nuclei are
absolutely identified as such). This is parsimonious with the CBR theory, which
has other important implications for the Standard Model, early universe
cosmology, and the origin of matter and anti-matter. This builds off of Tipler
and Piasecki (2018), where we have reviewed UHECR data from the Southern
Hemisphere to get a 86\% success identification rate. We predict that the
remaining UHECR not paired with a potential source will have sources identified
upon closer telescopic investigations of these regions. Other recent
experiments further suggest an SU(2) dominant composition of the CBR photons.
The problem of UHECR origin may be solved.
