Moshe Carmeli, John G. Hartnett, Firmin J. Oliveira
TL;DR
This paper derives a universal formula linking cosmic time to redshift, enabling precise time estimation at any redshift level, except at the Big Bang where redshift diverges.
Contribution
It provides a new, general formula relating cosmic time to redshift applicable for all redshifts, extending previous models.
Findings
Formula valid for all redshifts
Time can be traced back to any redshift except infinity
Enhanced understanding of cosmic timeline
Abstract
In cosmology one labels the time t since the Big Bang in terms of the redshift of light emitted at t, as we see it now. In this Note we derive a formula that relates t to z which is valid for all redshifts. One can go back in time as far as one wishes, but not to the Big Bang at which the redshift tends to infinity.
