H_o = 71 km/s/Mpc

I just wished they'd used some more 'natural' units. Mixing
two different units of length in the same parameter just obscures
what it really says:

H_o = 1/(age of the universe) or H_o = c/(radius of the universe).

Much clearer, no?

Quasars had a comon origin at the Big Bang. Their red shift is
gravitational and motion. They are distributed throughout the entire
universe.
