If I am measuring the expansion from earth I would find the Hubble Law to apply. If I switch positions and locate myself to a far distant galaxy and then measure the expansion I would also see the Hubble Law apply. In other words I will see the universe expand faster the farther out I look no matter where I am. I assume this to be true.
There is no center since everyone else will see the same expansion from their "center" so in a sense all points are "centers".
Usually I see in "books" a physical analogy of "raisin bread dough expanding while cooking in the oven." This analogy disturbs me since it would not explain how Hubble's Law would apply no matter where you measure from.
Is there some other fundamental feature of space here that I am not understanding ?
