Name[edit]

I thinnk Geometry_of_the Universe.jpg makes more sense as a title. The figure has nothing to do with the "End of" the Universe. --74.109.155.80 22:18, 15 January 2007‎

I fully agree, it's difficult to find it with this title--RealSebix (talk) 11:50, 12 February 2012 (UTC)[reply]

The given source-URL is wrong! --RealSebix (talk) 11:47, 12 February 2012 (UTC)[reply]

Figure has an error[edit]

The jpg is shown as a figure on the Wikipedia page "Flatness problem". This shows three different geometries based on curvature: positive, negative and flat. For each of these geometries, a triangle is shown. The triangle for the negative curvature is wrong. The sum of the degrees for the three angles in a triangle on these three geometric surfaces should be respectively: >180, <180, =180. The triangle shown for the negative curvature erroneously has a angles adding to >180, like the positive curvature triangle.

The figure is attributed to NASA, with permision from Gary Hinshaw. BuzzBloom (talk) 17:59, 20 March 2015 (UTC) BuzzBloom[reply]
