And the third problem is that the distance between the sun and the earth at time t = 0 was not zero. And the fourth problem is that he doesn't understand what km/s/Mpc really means, making his numbers extra silly. And so on and so forth. My suggestion is not to bother with trying to correct him - life is much too short to take on such a herculean task.
That's actually not a problem for my math, but for Inflationary Theory. Inflation is already coming up with 123 AU's (instead of 1 AU) between the Earth and Sun (with distance 0 at t=0).
Starting with a larger distance just increases Inflationary Theory's error...disproving it further.
