The Meaning of It All

Hubble’s Constant: H0 = 42!

42 scots miles/sec/Mpc that is.

Finally we know the natural units for cosmology.

    Doesn’t this translate to 76 km/sec/Mpc?

    bit less than that – well within 1 σ of the nominal value…

    Perusal of Wikipedia does not indicate an already defined mile that makes H0 = 72 km/s/Mpc translate into 42 miles/s/Mpc. Therefore, I think we need to define the cosmological mile (or “natural” mile) that is equal to 1714 m. This transformation is quite appealing, IMHO, because it is linear and because it is aesthetically pleasing. Perhaps someone will next write down the equation of state of dark energy in these “natural” units.
