A Critical Examination of Cosmic Expansion and the Present-Day Origin of the CMB

[Classical Motion]

I think that the temperature of space is a dormant temperature. An abstract temperature. The CMBR is a dormant temperature. An inactive temperature.

I bought a “cat pak” of lasers. Red, green and violet. There is no interaction between these lasers when criss-crossed. No mixing. No loss. No change. They pass right thru one another WITHOUT interference.

But if I put a laser or criss-cross the laser on a thermometer bulb…… then there is an interaction. Mass must be present for CMBR to mean anything. To interact.

Static and the CMBR is only a potential for temp. Not temp itself.

CMBR is omni-directional. No net direction. Only an angular receptor can make use of and interact with it.

Personally, I think CMBR is local and present. Possibly some harmonics of gravity. I think gravity comes from dipole vibration. Not a fundamental particle property.

Just supposition, of course.

Duty cycle light. Discreet intermittent wave fronts. Blinks. Duty cycle blinks. With two discreet shifts. An emitter shift and a detector shift. A ratio shift and a rate shift.

The only difference is that instead of regarding the CMB as relic radiation, AND Theory holds that it is dark matter which is the relic radiation from the Big Bang.

If DM is the source of the relic radiation, and because all radiation propagates through space, then only the local DM would give us the strange 2.73K result. The more distant sources would show cooler regions.

This assumes we are in an expanding universe, of course. To claim there is no expansion requires refutation of all the lines of evidence that have been found, over and over, to support expansion.

Thanks for considering the possibility that the CMB is a present day phenomenon

The CMB is the cornerstone of cosmological expansion theories

It's certainly the best evidence for the theory, which began in 1927 and was deemed likely a few years later by many prominent cosmologists including de Sitter and Edington. Einstein soon followed.

But more predictions came forth as scientists began to ponder the expansion theory. The CMBR became the key test.

Alternatives should always be welcomed, but supported.

Me: do we observe the CMBR as uniform or as a red shifted gradient based on distance?

AI: We observe the CMBR as highly uniform, rather than as a redshifted gradient based on distance. This is because the CMBR comes from a single, well-defined surface—the surface of last scattering, when the universe became transparent about 380,000 years after the Big Bang.

Why Isn’t There a Radial Gradient?​

1. We See the CMBR as a Background The CMBR originates from everywhere in the universe at once, but we don’t observe different distances affecting its redshift. Instead, it appears uniform because we are looking at a snapshot of the early universe.

Is this AI statement accurate?

 

[billslugg]

The AI response is correct, except it does not address the amount of nonuniformity or the dipole non-uniformity.
The CMBR is highly uniform, only 1 ppm unevenness.
The distance is the same everywhere.
The CMBR is slightly blue shifted, by about 500 km/s in the direction the Milky is moving towards Vega, and redshifted behind us.
This is an absolute velocity reference in the Universe, but there is no preferred direction or location.

AI: Yes, the Cosmic Microwave Background (CMB) radiation can be measured locally. It's a faint microwave radiation that permeates the universe and can be detected everywhere,

also the AI: The Cosmic Microwave Background (CMB) is measured from a very great distance, approximately 40 billion light-years away, representing the afterglow of the Big Bang.

i am a bit confused by this.

CBMR measures the same frequency locally as it does 40 billion light years away? Uniform without hubble redshift?
