Cosmic Time at Redshift Calculator

In cosmology, the cosmic time defines the time taken by the universe for its physical formation and development. This online cosmic time at redshift calculator can be used to calculate the cosmic time near the redshift z using the Hubble parameter at z. Enter the Hubble parameter in this online tool to estimate the cosmic time.


Result :



Calculate the cosmic time at the redshift of the Hubble parameter at redshift is 5 s-1


t(z) = 2 / (3*H(5))
= 0.133 sec
