The Hubble law

Area of Science:

  • Cosmology
  • Extragalactic Astronomy

Background:

  • The Hubble law is a cornerstone of modern cosmology, describing the expansion of the universe.
  • Discrepancies have been observed between Hubble law predictions and observational data for extragalactic sources.

Purpose of the Study:

  • To evaluate the consistency of the Hubble law and the Lundmark law with observational data.
  • To investigate the flux-redshift relationship and its implications for cosmological models.

Main Methods:

  • Analysis of complete samples of extragalactic sources across optical, infrared, and X-ray wave bands.
  • Statistical assessment of the Lundmark law's predictive power compared to the Hubble law.
  • Application of an optimal statistical method to account for flux limits in flux-redshift relation analysis.

Main Results:

  • Hubble law predictions show significant excess dispersion in apparent magnitude compared to observations.
  • The Lundmark law demonstrates consistency with observational data and explains deviations from Hubble law predictions.
  • The flux-redshift law F ~ (1 + z)/z aligns with observations, suggesting a spherical space model.

Conclusions:

  • The Lundmark law offers a more accurate description of extragalactic source observations than the Hubble law.
  • The observed flux-redshift relation supports a cosmological model with a fixed spherical space, potentially refining estimates of the universe's radius.
