Did Hubble can it wrong?

Secondly, the expansion of the universe has everything to do with redshifts.

You misunderstood me. I said there is evidence to support the the hubble constant that is independent of the wavelength shift, i.e. paralax, standard candles, etc... I was NOT saying that the universe is not expanding nor the redshifts are unrelated.

Okay, thanks for the clarification.

Yes, if we go through the route of parallax, standard candles, etc... we get that the universe is accelerating. If you read my blog carefully, the point I'm making is that this acceleration can be derived theoretically strictly from GR - that the observation through the route of parallax, standard candles, etc confirms that is obviously a good thing otherwise GR is in trouble. So you've got two pictures: one is that the universe is expanding, labelled that the Doppler Effect; the other is that the universe is not expanding, but the photon still exhibit a redshift due to the fact they are moving against gravity. On first appearance, these two pictures seem to contradict each other, but Einstein Equivalent Principle says they are equivalent -- you can trade one with the other, the equations describing them are the same.
