What causes redshift in a non expanding universe?
To follow on from previous articles on this blog describing how light and atoms are wave only and how the offset between emission and absorption spectra can be described by waves only, I would like to supply a possible explanation and mechanism for what could cause the redshifting of light in a non expanding universe. This mechanism that occurs between an atom and emr and leads to a redshifting of light between absorbed and emitted light is the same mechanism. But on a much smaller scale when light propagates through a vacuum.
Distributing higher energies received to lower energies transmitted by any point in space of the vacuum.
