Original research and synthesis
I'm posting here rather than the talk page of an anonymous editor. There are two (there are more) important policies for posting in Wikipedia articles. One is WP:OR (original research); essentially if you can't find a reliable source that backs up what you're posting, then short of the blindingly obvious (the sky is blue), you can't include it. A related policy is WP:SYNTHESIS (synthesis), other than straightforward calculations, you can't take claims from one reliable source together with claims from another reliable source to produce claims not contained in either source even if you can produce a highly logical argument for combining the two sources. Hence you can't take "the Gaia DR2 parallax and the Gaia DR3 parallax are dramatically different", and infer anything other than that at least one parallax is seriously in error. Even if you are a professional astronomer who "knows better". Find a reliable reference when you want to make claims like this. Lithopsian (talk) 21:00, 28 August 2022 (UTC)
 * A third policy is WP:BRD (bold, revert, discuss). This means you can post stuff boldly, even quite controversial stuff, accept that it may get reverted, and then be prepared to discuss it.  This avoids the gridlock of having to discuss everything in advance.  Simply re-inserting stuff over and over without discussion is a good way to get blocked.
