lidal Posted September 9, 2019 Share Posted September 9, 2019 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 ? “ Link to comment Share on other sites More sharing options...
Mordred Posted September 9, 2019 Share Posted September 9, 2019 Nope there are other pieces of evidence your obviously ignoring such as Baryon accoustic oscillations and spectronomy measurements of the metalicity of the CMB. Link to comment Share on other sites More sharing options...

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). Quote This theory may also explain the cosmic x-ray background radiation, which is proposed to be Doppler (blue) shifted light from approaching superluminal galaxies. 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.) In summary: Quote Can the CMBR be just Doppler shifted light from receding superluminal galaxies ? No. Link to comment Share on other sites More sharing options...

The em radiation from a galaxy receding at superluminal speed would never reach us, so that can't be what the CMBR is. Link to comment Share on other sites More sharing options...

"we can observe galaxies that have, and always have had, recession velocities greater than the speed of light." https://arxiv.org/abs/astro-ph/0310808 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. Link to comment Share on other sites More sharing options...
