In his most recent, Ned Wright gives the best fit Omega as 1.011.(adsbygoogle = window.adsbygoogle || []).push({});

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.
