What correction must be made to the estimate of the age of the universe that we derive by measuring the Hubble constant?

    More galaxies exist in one direction from the Earth than other directions.
     Space itself has a curvature that depends on the total amount of mass in the universe, which is poorly known.
     Time has been slowing down since the beginning of the universe in the Big Bang.
     We are not located at the center of the universe, so space in our vicinity is expanding at a different rate.
     The Hubble constant depends on the distance of the observed source from Earth.
