thread_title:  Inconsistent 

message: I'm a little unsure as to the purpose of this idea. Is it simply to help humans conceptualize the vast spans of time in Cosmology?
Something to this effect should be added to the article by somebody who actually knows anything about this. Lesmothian (talk) 19:37, 6 November 2009 (UTC)
thread_title:  Purpose? 

message: It would be interesting to give this information in the article. Was Sagan the inventor or just the main "popularizer"?  —Preceding unsigned comment added by 87.219.165.19 (talk) 09:28, 10 November 2010 (UTC)
thread_title:  Who invented this scale? 

message: Around 1750, Franz Josef Haydn  establishes and popularizes new forms of musical expression from which practically all structured later classical music descend. The break between baroque and rococo music is huge. Pbrower2a (talk) 03:07, 24 April 2015 (UTC)

message: The first reference about the Cosmic Calendar that is apparently supposed to be an "activity" (according to the URL), gives a 404.  — Preceding unsigned comment added by 210.55.200.172 (talk) 22:28, 22 June 2016 (UTC)

message: Propose deleting this section as it is highly subjective, doesn’t cite sources and once you get into cosmological years written in as powers of 10 it ceases to fulfil the stated purpose of making the scale intuitive. Btljs (talk) 20:29, 19 October 2021 (UTC)
