Thank you for the really good explanation. I find it amazing that E. Hubble has drawn a straight line through the pile of dots. Not easy to see, I find.

The universe is still unfolding, and faster all the time. Nice!

The Universe is expanding at least for now...could it be that after enough black holes combine or merge that eventually a super massive black hole could cause another Big Bang ....a cyclic, recycled universe which would follow along with the ideas that matter and energy and thus information is never essentially destroyed...
