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!
Jane Lubenskyi
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...

Fantastic and clear

Thanks to Prof. Adam Reiss for thee audit! The raisin loaf keeps rising. Parallax for distancing. Light houses or 90 km laser sun. Fog horns, objects of known size. Super novae as standard candles. Redshift expansion of space. Edwin Hubble`s efforts. Running the movie backwards for an age and inverse guess of the universe age. Hubble found 2 billion years- he was off.
