This article is out of date. The expansion rate of the universe is now known to be accelerating, not slowing down. The article needs to be rewritten or deleted.

for the missing citation about the omega value, one could propably use the 2015 Data from the plank spacecraft; it has already been linked elsewhere on wikipedia, but i don not feel qualified to do so.

This comment moved from the body of the article to here:
The article appears to be inconsistent in its discussion of omega.
It first states: "If omega is more than one, the universe will eventually stop expanding and will thus collapse in on itself to again form another fireball not unlike the one from which it came."
Then, five sentences later it states: "The universe's rate of expansion is accelerating and is projected to continue accelerating due to dark energy, thus omega must be greater than 1."
