The metric expansion of space is a fundamentally different phenomenon than the relative motion of two objects in the flat spacetime of Special Relativity: While special relativity constrains objects in the universe from moving faster than the speed of light with respect to each other, it places no theoretical constraint on changes to the scale of ...
Because space itself was expanding faster than the speed of light. Which is perfectly acceptable by the way with Special Relativity, because the speed of light is only a barrier for matter traveling through space. There is no such limit for the speed with which space itself can expand (or contract), as far as I know.
I had the same question after watching Dr. Paul J. Steinhardt's talk at Vanderbilt http://www.youtube.com/watch?v=IcxptIJS7kQ This gentleman teaches Big Bang Cosmology in Ireland and says the Planck data's non-Gaussian results put a kink in the ekpyrotic models. http://coraifeartaigh.wordpress.com/2013/03/28/planck-and-the-inflationary-universe/ In Dr. ...
