To what degree is the microwave background radiation isotropic to its precursor, neutrino production?
Loren Booda said:Our planet has a significant peculiar velocity relative to the Microwave Background Radiation (era of photon decoupling). I was wondering whether it could be theoretically determined if the same velocity applied to the overall production of neutrinos during the primordial production of protons (era of neutrino decoupling).
The relative peculiar velocity of the cosmic microwave background radiation (MBR) and the neutrino background is the difference in their velocities as observed from a stationary point in space. It is a measure of how fast the two backgrounds are moving relative to each other.
The relative peculiar velocity can be measured using redshift data from the cosmic microwave background and the neutrino background. By comparing the redshift, which is a measure of how much the light from these backgrounds has been stretched due to their motion, the relative peculiar velocity can be calculated.
The relative peculiar velocity is caused by the expansion of the universe. As the universe expands, objects that are far apart from each other will have a higher relative velocity compared to objects that are closer together. The MBR and the neutrino background originate from different distances, hence their relative peculiar velocity.
The relative peculiar velocity can provide valuable insights into the early universe. It can help us understand the conditions and processes that led to the formation of these backgrounds. It can also give us clues about the density and distribution of matter in the early universe.
No, the relative peculiar velocity is not constant. It varies depending on the distance between the MBR and the neutrino background, as well as the expansion rate of the universe. As the universe continues to expand, the relative peculiar velocity will also change.
