In his most recent, Ned Wright gives the best fit Omega as 1.011.
He hastens to say that since the fit is not all that better than for Omega exactly 1, space being flat infinite, one cannot rightfully conclude that Omega > 1.
However suppose, simply as an intellectual exercise, that one were to take this best fit Omega literally on its own terms. Imagine that the U really is as Wright has determined.
Then we imagine space as a bumpy dimply THREE-SPHERE, and the radius of curvature, or the actual fourspace RADIUS if you like to picture the threesphere living in a boyscout Euclid fourspace, is 130 BILLION LIGHT YEARS.
Try it on, and if you like the fit, wear it.
