Hubble's law

n.
An empirical law of observational cosmology stating that the velocities at which galaxies in the universe recede from one another is directly proportional to the distances between them.

[After Edwin Powell Hubblewho first formulated it.]

Hubble's law and the Doppler effect, observed in nearby stars, suggested that stars moving away shift toward red, and the faster the stars move away, the greater the shift.
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.
This book examines forty eponymous laws of science, from Archimedes' Law of Buoyancy to Hubble's Law of Cosmic Expansion and the great minds behind them.
Doesn't that contradict Hubble's law, which states that distance is correlated with age?
Despite the acceptance of the Doppler redshift described by Hubble's law, there are problems with this model.
