The actual CMB temperature is thought to be ~3000 K with a redshift of z = 1089, but that result comes from a specific model that is the CDM (cold dark matter) big bang cosmology. In the big bang, the CMB would be expanding at 99.91%c, but different cosmologies result in a range of predictions and the shrinking universe has a really cold interpretation for the CMB, just 0.64 K at z = 1089. In today's epoch, this temperature would be equivalent to the ionization energy of hydrogen at 13.6 eV, which is 158,000 K...a little bit warmer than the CMB.
In addition, very slight CMB temperature difference is called the CMB dipole, points the direction that the earth is moving through the cosmos. This arrow of time shows our path through the cosmos and defines both an origin and a destiny.
The CMB arrow shows where we came from, i.e. our origin, as well as where we are going, i.e. our destiny. Hurtling through space at 830,000 mph (371 km/s) means that we quickly leave the space of each moment behind and for each moment of thought, about 0.6 s, we move about 130 miles through the karma of the universe even though we imagine ourselves standing perfectly still.
If you ever feel like you are not going anywhere, now you can rest assured that we all are on a grand journey together through the karma of the universe and mom and dad, mother earth and father time, are driving. We note our karmic journey on March 11th and September 10th, the days where the sun and earth are best aligned with the CMB time arrow that points the destiny of the universe.
This diagram is called a Mollweide projection of the entire sky that shows how the cold blanket of the finite CMB creation dipole wraps all around us. Up and down are the 180 degrees of up and down from the plane of the galaxy and left and right are the 360 degrees as the Milky Way also wraps all around us.
In a shrinking aether universe, interpretations of cosmic objects like the CMB vary h, c, and alpha and a shrinking aether universe is much different from an expanding universe. Aether temperature, Tae = T (1+zae)/(1+zH), is a scaled cosmic temperature from the present epoch. Instead of the CMB rest frame temperature being 3,000 K as 2.7 K * (1 + zH = 1090), the aether CMB temperature is just 0.64 K, which is 2.7 K x 260 / 1090 = 0.64 K in the aethertime rest frame for the CMB. The CMB motion is 0.24c towards us, which blue shifts the 0.64 K rest frame CMB to our 2.7 K rest frame all in aethertime.
The aethertime creation CMB is very close to the edge of the universe and represents cae = 0.062 c, just 6.2% of c in the current epoch and so force is also just 6.2% of that of the current epoch. Atomic time periods increase as atomic force decreases, and eventually universe time transitions from atomic time to aether decay time. Thus in aethertime, the singularity known as an event horizon simply represents the boundary of the shrinking aethertime universe.
This interpretation of an aether event horizon differs sharply from that of spacetime and GR of mainstream science. Correspondingly, the event horizon of a singularity known as a black hole represents a similar transition from atomic time to aether decay time and the boson matter inside of a black hole is simply the same boson matter that makes up all of the universe.
The fermion accretion disk of a black hole represents the same kind of boundary for a black hole as the CMB does for the universe, but now shifted from 0.64 K to the temperature 13.6 eV energy of hydrogen today. This energy corresponds to ultraviolet spectra called the Lyman series and Lyman blobs are often seen in the early universe with z > 2. In fact, a very large Lyman alpha blob called Himiko appears in the very early universe at z = 6.6 and is thought to represent a nascent black hole and galaxy.
