 05:23: More accurately, they analyzed what we call the power spectrum.
 05:47: We talked about the power spectrum in enormous detail in that earlier episode.
 05:52: One thing that we didnâ€™t talk about is how gravitational lensing influences the overall shape of the power spectrum.
 06:22: ... of the CMB, this results in a sort of smoothing or blurring out of the power spectrum the peaks are less sharp than they would be ...
 07:25: They found the range of models that fit the shape of the power spectrum, and for the most part those pointed to positive curvature.
