Caution: The 'P' Hubble distance
calculator is based upon a non-mainstream
distance formula which is intended to eventually replace the Hubble distance formula and its expanding universe cosmology the Big Bang. Its calculations were derived from an alternative cosmology called the Pan Theory which requires its own equation resulting in greater calculated distances than the Big Bang model using the Hubble distance formula based upon Special Relativity. This formula was refined and tested against hundreds of type 1a supernova observations showing them to be true standard candles, contrary to the need for dark energy to explain observations.
For this alternative cosmology the cause for the observed cosmic redshifts would be the diminution of matter rather than the expansion of space. It is a type of scale-changing theory and steady-state cosmology. The universe would not be expanding, instead matter would be very slowly getting smaller which would give the appearance of an expanding universe. At the same time new matter would be created from the decrement maintaining a generally constant universe density.
The 'P' Hubble distance formula, like
the Hubble distance formula, proposes that the distance to a given galaxy is proportional to the redshift of its observed wavelengths. The redshift of the spectral lines is commonly expressed in terms of the "z" parameter, which is the measured change in length of the observed wavelengths.
The 'P' Hubble distance is given by the formula below (where Po is a constant = 1,958.3, and "z" is the redshift value). Click on the redshifted wavelength value after entering it, to calculate this page. :
