How flat can you get? A model comparison perspective on the curvature of the Universe
http://arxiv.org/abs/0901.3354"
In it the authors say "We show that, given current data, the probability that the Universe is spatially infinite lies between 67% and 98%". By spatially infitite do they mean that the curvature is exactly zero (omega = 0)?
All classical physical measurements have a range or nonzero tolerance.
Omega = 1.01 +/- 0.02 means that Omega = 1 is POSSIBLE - universe might be infinite
Omega = 1.01 +/- 0.005 means that Omega = 1 is IMPOSSIBLE - universe is finite
This is primary school reasoning. Their probabilities are rubbish.
