Can the CMBR be just Doppler shifted light from receding superluminal galaxies ?

A speculation on CMBR :

The CMBR may be Doppler (red) shifted light from receding superluminal galaxies.

Due to the high relative velocity of some galaxies, Doppler effect can cause visible light to be

 shifted down to microwave frequencies.

This theory may also explain the cosmic x-ray background radiation, which is proposed to be  

Doppler (blue) shifted light from approaching superluminal galaxies.

 

My paper is found on Vixra:

“Can the Cosmic Microwave Background Radiation be Doppler Shifted Light from Receding Superluminal Galaxies ? “

Why superluminal? Have you calculated the amount of red-shift (and the corresponding velocity) to convert the visible light from galaxies to microwave radiation? If so, please show us the calculations.

How would the spectrum of light from galaxies be turned into a near-perfect black body spectrum by this process?

What is causing the galaxies to recede at these massive velocities?

a) If it is because of cosmological expansion, then you need to explain why the predictable processes in the early hot, dense galaxy did NOT produce the CMB as basic physics requires.

b) If this is not because of cosmological expansion, then you need to explain how galaxies can move faster than light (something forbidden by special relativity).

Many of the same questions apply.

Why superluminal?

Why are they moving at this speeds?

Why have we no collided with any of these galaxies moving at superluminal speeds?

How are they violating SR?

Does the spectrum of the X-ray background match the shifted spectrum of starlight?

What, exactly, is wrong with the current mechanisms for producing the X-ray background.

 

In all answers, please show your working. (Yes, it is like being back at school.)

No.

The em radiation from a galaxy receding at superluminal speed would never reach us, so that can't be what the CMBR is.

"we can observe galaxies that have, and always have had, recession velocities greater than the speed of light."

That is assuming an expanding universe. It isn't clear if the OP is trying to deny expansion. But if so, it wouldn't be possible for galaxies to be receding faster than light.

I was wrong again.  Thanks for the link.
