Thus the  universe was known to be flat to within about 15% accuracy prior to the  WMAP results. WMAP has confirmed this result with very high accuracy  and precision. We now know that the universe is flat with only a 0.5%  margin of error. This suggests that the Universe is infinite in extent;  however, since the Universe has a finite age, we can only observe a  finite volume of the Universe. All we can truly conclude is that the  Universe is much larger than the volume we can directly observe.<a href="http://map.gsfc.nasa.gov/universe/uni_shape.html" target="_blank">http://map.gsfc.nasa.gov/universe/uni_shape.html</a></blockquote>
