If the density of the universe is equal to the critical density, and H equals 50 km/s/Mpc, then the true age of the Universe is 13.3 billion years.

The age of the Universe can be estimated using the Hubble constant (H), which in this case is given as 50 km/s/Mpc. The formula to estimate the age of the Universe is approximately $1/H$. If $H = 50$ km/s/Mpc, converting units to years gives an age of about $1/(50 \text{ km/s/Mpc}) \approx 19.6$ billion years, not 13.3 billion years.
