Space: Infinite? Not so much.

For a variety of reasons I’m allied with the notion that space is finite and discrete. Both of you that follow my blog know that we’ve already discovered that there are “holes” in the CMB; now they’ve got an alternative to the “flat” space geometry that has held sway to date, namely the Poincare Dodecahedral Space Model. The part of the article I like is:

the data delivered between 2003 and 2006 by the NASA satellite WMAP, which produced a full-sky, high resolution map of the Cosmic Microwave Background Radiation (CMB), yield a very poor fit to the concordance model at large angular scales. They rather tend to favour a finite, positively curved space, and provide hints about a multiply-connected topology. [full story]
