Please help. Astronomy question?

Assuming the universe began expanding when it came into existence and that it has always expanded at a constant rate, what would the age of the universe be if the Hubble constant was measured to be 62 km/s/Mpc?


Also answer has to be in billions of years. Thanks

    Constant rate expansion disobeys all known laws of physics.

    The Hubble constant works for visible univers, but has a bad flaw, Einstein proved that.

    The universe itself keeps on expanding and expanding

    In all of the directions it can whizz

    As fast as it can go, at the speed of light, you know

    Twelve million miles a minute, and that's the fastest speed there is

    So remember, when you're feeling very small and insecure

    How amazingly unlikely is your birth

    And pray that there's intelligent life somewhere up in space

    'Cause there's bugger-all down here on Earth!

    62 km/s/Mpc, better expressed as (to avoid ambiguity)

    62 (km/s)/Mpc or 62 km/s•Mpc

    1 pc = 3.09e13 km

    1 Mpc = 3.09e19 km

    62 km/s•Mpc x 1 Mpc / 3.09e19 km = 1.94e-18 km/km•s = 1.94e-18/s

    inverting we get 5.15e17 s

    or 1.63e10 yr

    or 16.3 billion yr
