I am puzzled by the latest results of the MAP experiment and the evidence of an accelerating Universe. The MAP result shows that the Universe is flat (//map.gsfc.nasa.gov/) My question is: How can it be flat AND accelerating? In discussing the flatness of the Universe, Georg Gamow, in his "Mr Tompkins in Paperback" (page 28) states: "Suppose you have objects distributed uniformly through space... and suppose you count their number within different distances from you. If this number grows as the square of the distance, the space is flat; if the growth is slower or faster, the space possesses a positive or negative curvature." Surely, an accelerating Universe gives a negative curvature to space? Thanks for an interesting and informative website. Regards, Ed Brown
