The expression found, equation (13), is a generalization of Hubble's law.
Firstly we discuss the unreasonable results caused by Hubble's Law.
We call this relation Hubble's Law, but it could just as fairly be called Lemaitre's.
Doesn't that contradict Hubble's law, which states that distance is correlated with age?
Specifically for the cosmological data, the law of selfvariations predicts and justifies: the redshift of distant astronomical objects and Hubble's law, the cosmic microwave background radiation, the large-scale structures of matter in the Universe, the fact that the Universe is flat, the fact that the total energy-content of the Universe is zero, the fact that the very early Universe went through a phase of ionization, the arrow of time in the macrocosm and its breakdown in the microcosm, the fact that the luminosity distances of distant astronomical objects will always be measured larger than the actual distances.
Now known as Hubble's law, this finding provided the first observational evidence that the universe isn't static, but instead expands over time.
Hence the Hubble's law must be re-interpreted as "at present as galaxy distance increases its revolving speed increases".
The discovery of this remarkable linear relationship, now known as Hubble's law, supplied evidence for the notion of an expanding universe.
This linear decrease in energy is interpreted as an increase in redshift or a linear increase in velocity with distance by Big Bang (BB) theorists and amounts to the linear portion of Hubble's Law.
Currently, Hubble's law is often considered as the observational evidence of an expanding universe.
