Without what reservations?
Until they could measure the dimness difference of fading super
nova light there was no way of determining speed up or slow down
(as per news releases a week ago). The speedup was confirmed by
three different groups ...MIT (the results of Robert Kirshner
and his team) , a university in Italy and another I cannot remember).
Memory not so stable anymore
Some overly poetic ... From my "Aunti Gravie" posting on March 1-
"Enlightened by the spent matches of super novi, several search
teams have cautiously agreed that the parting of the evolving
universe is *speeding up* ...........
It is now, perhaps, believed that the hidden spirits of space
encourage such galactic va-va-voom by tossing out and at it, an own
eternal supply of opposing gravity ....cosmic vectors, vaporing out
ever smartly. Such "quintessence" of "star-mind-will", as virtual
pearls winking in and out of existence, do quiver quiet each to
an own gravity rhythm.......

MB> If the universe is not static (and it isn't) then there is no 5th force:
If I read it right, the speed up is added to the separation
speed. Though the news briefs mentioned the resurrection of the
"cosmological constant" ...Einsten maybe a little wrong?, they
did not explain its present implication in the speedup.

Mark! You speak with a scientific authority that would make one
believe an angel is whispering into your ear. For us less plugged
into the celestial spheres, we read the latest as mortals, "sort
of believing" what we read until the next of a thousand shoes fall.
As methods and tools improve, many new views will emerge. There are
few "knowables" that stay "absolute" (even gravity may have some
skeletons in the closet!).
....we might wait and see ??? @@ ... Dave
P.S. Announced tonight! ....a big rock swimming through space
that might catch our attention in a few years!
