With all this talk about units, I would like to mention that Google ever-so-helpfully says that 1 km/s/Mpc is "3.24077929e-20 hertz".

I see two things to comment on about Dave's response. First, if everything measured always shows the same velocity, then the "per megaparsec" part of the result becomes largely irrelevant, as Dave's results are the same regardless of this value. This means that Dave's results are "it doesn't matter how far away, it is all 85 MPH!" If taken seriously, this would be a challenge to the standard model of an expanding universe much bigger than the actually existing controversy. | I see two things to comment on about Dave's response.
