    Yes, but "accelerate" is a tough word in this context. It is important to realize that the expansion of the Universe is not moving galaxies through space, but rather it is stretching the space between the galaxies (so you're not sliding the galaxies over the top of the graph paper, but simply stretching the graph paper -- the galaxies don't move with respect to the lines). So your statement would be true even if the expansion rate of the Universe remained constant.

  • I HAVE MY OW THEORY ,I THINK TO KNOW WHATS CAUSING THIS EXPANSION

    BUT I HAVE TO MAKE MY OWN VIDEO, I DON'T KNOW WHEN BUT I'LL MAKE ONE. I ALSO THINK TO KNOW WHAT'S MAKING THE LIGHT TRAVEL POSSIBLE

    AND LAST, THE SHAPE OF OUR UNIVERSE.

  • That was the most clear explanation about the Hubble law that I've seen in my entire life... very good job!

  • Are the velocities of the galaxies constant throughout time, or do they accelerate? It would seem that for this law to work they will need to accelerate from each other - because if we take two galaxies for instance, after a certain amount of time they will have travelled a large distance away from each other. And the law states that their velocities should have also increased proportinally with distance. Is this a valid statement?
