The "Axioms" Of Nature

Not to drag us off topic, but: What I understood from my intro astronomy class is that this question has been answered. The universe will keep on expanding because the constant you mention is either zero or negative--based off of all the supernova data we've gathered. wiki has a nice chart here: File:Universos.gif - Wikipedia.
Notice how for the universe to shrink it has to be younger than the universe as currently measured (chart doesn't give the times, but my astro book did. iirc, the universe should only be about 7 billion years old if the constant is greater than 1. The universe, indeed, is older).Of course, I could be entirely wrong as I'm not studying to be an astrophyscicist. This is just what I remember from class last semester.

Christ am I glad I'm an IR/Hist major. Fascinating link, even if most of it went over my head during the first read through. The way I read it though is that we're pretty much positive that the universe will expand indefinitely. given that I didn't even see the difference between lambda and omega (though I should have), my statement is suspect.Now back to the regularly scheduled program "Tautology =/ Axiom", featuring D "A v ~A" Bertot and R "logician"Rhain.
