As I understand it, when observing different regions of the universe we get a different rate of expansion (the two Hubble constants), specifically the more distant observation seems to return a lower expansion rate.

So my question is could this be evidence for our universe expanding at different rates depending on the region we are observing?

Could the difference in temperature and density of different regions, observed in the cosmic microwave background, be the reason for different expansion rates, just as a cake in the oven will expand at different rates depending on its temperature?
