I'm not convinced that your proposition is correct. I realize that cosmologists use a lot of simplification in their descriptions, for friendly reasons, but I always prefer to keep things fairly straight. It is my reading of Hubble that he postulated that remote galaxies were receding -- at the time they emitted the light which we are now receiving -- from us at a speed which was proportional to the distance from where they were then to where we are now. How one interprets the concept of distance, in view of the separately postulated "expansion of space" and time-dependence of the "scaling factor" is obviously now a compounding, related issue, which lay outside Hubble's purview. Hubble's law does not specify, based upon the observed redshift (whether non-Doppler or not) what is (i.e. is now) the distance between us and the galaxy. It is considered simplest to assume that the velocity of separation is and continues radially uniform, and therefore has increased during the time it took the light to reach us. If you need to know the current (our observing time) location of the remote galaxy and the velocity of its separation from us now, you will need to apply further calculations to the Hubble data.

distance
Why is Edwin hubbles invention important?
=Edwin Hubble's invention is important because the telescope its self showed over 50,000 space galaxies and planets. also it was made of cats=
Why do observations made of distant galaxies indicate that dark energy exists?
The observations made from distant galaxies suggest that Dark energy exists. This is because of the fact that the galaxies are moving away from each other. This is given by Hubbles law.Instead of being attracted by the force of gravitation,galaxies tends to move away suggesting the presence of a gravity opposing force called dark energy.
What did Edwin Hubbles discovery of red shift demonstrate?
Edwin Hubble didn't discover redshift. What he did was make a systematic statistic of redshifts and blueshifts, of known galaxies. What this demonstrated was that the Universe is expanding.
The implication of hubbles law is that the universe is?
That it is expanding.

How old is the universe in 2011?
By using a therom call hubbles law and hubbles constant this is the calculation: 1/Ho=d/v=t t= 3.09x10 22/71000x31566926 t=13.738 billion years old
What does Hubbles law tell us about the beginning of the universe?
It shows that in the past, galaxies were closer together; also, it suggests - as is commonly believed nowadays - that some time in the past, all matter in the Universe was very close together, in a very hot and dense state.
