*From*: "John S. Denker" <jsd@MONMOUTH.COM>*Date*: Mon, 12 Feb 2001 15:47:53 -0500

Earlier I tried, with less skill than one might have hoped, to explain that

it is possible to imagine a 100% Newtonian expanding universe.

If you say it carefully, it's true. It suffices to imagine a universe

where things adhere strictly to the Hubble law: velocity proportional to

distance.

I think this is important for pedagogical reasons, to de-mystify the basic

expansion idea.

At 03:04 PM 2/12/01 -0500, David Bowman quite correctly pointed out that in

our non-imaginary universe we have additional observations; among other

things, we can observe deviations from the Hubble law.

He also pointed out that a nonzero value of the Cosmological Constant is

non-Newtonian.

Questions for David: What value of the CC do you think is right? How well

established is this value? With what confidence can values with the

opposite sign be excluded? (The last time I knew, if you asked 3

astronomers you would get 5 different CC values, and you could get several

more if you asked them again a year later.)
