The type Ia supernovae and the Hubble's constant

TL;DR

This paper argues that the Hubble's constant varies with line-of-sight plasma density and galaxy properties, supporting plasma-redshift theory over the big-bang model, based on analysis of type Ia supernovae data.

Contribution

It introduces plasma-redshift theory as an alternative explanation for redshift variations and challenges the assumption of a constant Hubble's constant in standard cosmology.

Findings

Hubble's constant averages 59.44 km/s/Mpc in intergalactic space.

Significant variation of Hubble's constant with galaxy redshifts and galactic latitude.

Absence of time dilation effects in type Ia supernovae measurements.

Abstract

The Hubble's constant is usually surmised to be a constant; but the experiments show a large spread and conflicting estimates. According to the plasma-redshift theory, the Hubble's constant varies with the plasma densities along the line of sight. It varies then slightly with the direction and the distance to a supernova and a galaxy. The relation between the magnitudes of type Ia supernovae and their observed redshifts results in an Hubble's constant with an average value in intergalactic space of 59.44 km per s per Mpc. The standard deviation from this average value is only 0.6 km per s per Mpc, but the standard deviation in a single measurement is about 8.2 km per s per Mpc. These deviations do not include possible absolute calibration errors. The experiments show that the Hubble's constant varies with the intrinsic redshifts of the Milky Way galaxy and the host galaxies for type Ia supernovae, and that it varies with the galactic latitude. These findings support the plasma-redshift theory and contradict the contemporary big-bang theory. Together with the previously reported absence of time dilation in type Ia supernovae measurements, these findings have profound consequences for the standard cosmological theory.
