The Cosmic Time in Terms of the Redshift
arXiv:gr-qc/0506079 · doi:10.1007/s10702-006-0518-3
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.
