	The explanation of the title text is now long and complicated and, for me, hard to follow. Couldn't we just say something simple like this? "Randall's universe diagram is always at least one pixel thick. But the universe started much smaller than one pixel and expanded to the size it is today, so at some time instant it must have passed through the size of Randall's diagram -- making the diagram 'actual size' at that instant." Wouldn't something simple like this be better? I'd do this myself but I'm leery of deleting a lot of other people's writing.

 "The title text is a mathematical joke, based on the Intermediate Value Theorem (IVT)...

 :Even with antialiasing, the intrinsically granular nature of the graymap representing a sub-pixel measure, at any given perpendicular point of the scale at any given device's DPI.  I wouldn't put it past the Universe to have skipped-through the gap between values.  ...on the other hand, if we get into Big Rip territory, perhaps the effective DPI of any extant representation ''will'' pass back through a coincident value.

 It would be good if this clarified whether the diagram of the growth itself is correct and just badly mislabeled, or if it doesn't even correctly show the size of the universe over time. [[User:Gaelan|Gaelan]] ([[User talk:Gaelan|talk]]) 00:24, 12 December 2019 (UTC)
 :No, this is not the actual diagram, which is a much smoother regular bell shape without the sharp pointy left end.  We also don't really know anything about the starting point beyond wild conjecture, as there's lots of uncertainty in the cosmological model, no matter what anyone says.

 While the explanation mentions the dashed lines for the future fate of the universe, it only lists 3 possibilities, even though there are 4 sets of dashed lines in the diagram. It's possible that the outermost dashed lines represent another mistaken inflation button press. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 03:16, 12 December 2019 (UTC)
