That is the idea. Either it is the age of the Universe or the time limit of the observable Universe, but not both!

]]>Er. The age of the Universe is only fixed in the Big Bang theory once the Hubble constant is determined. Your argument, as far as I understand it, is therefore circular.

]]>As these calculations approach the speed of light throughout the age of the universe, we can do the inverse calculation to determine the average increase in the velocity of expansion so that the observable universe is of the age stated by the Big Bang Theory.

The result is 300.000 km/s /(13.799/3,26) Mpc =70,820 km/s Mpc. https://molwick.com/en/gravitation/072-gravitational-waves.html#big-bang ]]>
