Adherence to the Scientific Method

Undoer' seems to think modern cosmology is devoid of the scientific method, that General Relativity requires no falsification condition.

If this is the case, modern cosmology belongs in the religious portal, not the science.

The falsification condition of General Relativity was the Galaxy Rotational Problem, it is necessary to mention this or GR is unfalsifiable pseudo-science. A hypothesis such as dark matter or black hole, with the expressed purpose of salvaging GR, is the classic definition of goal-post moving. — Preceding unsigned comment added by 120.28.231.216 (talk) 08:19, 16 January 2019 (UTC)[reply]

WP is no forum for general discussion, we give overview of what sources say. Your edit was POV and revert by the editor was justified. ThanksAhmadLX (talk) 10:54, 16 January 2019 (UTC)[reply]

unsigned has a point that applies to many of narratives of GR and QM. It needs to be made clear where theory does not match experiments and the linkage to other theories that adjust or tune for the discrepancy. For example, if science were to find that a graviton plasma permeates the universe it would cause major demolition, recasting, and reframing to many narratives and theories.

Changing template message

Hello all, I removed some of the template messages on this page because the one saying this page needed expert attention seems to be outdated, if anything, because a lot of the equations on this page are currently accepted. Additionally, the lead does actually summarize the article, and the concept in general. Thanks!

Further investigations

" Comparison of rotating disc galaxies in the present day (left) and the distant Universe (right).[21] The rotational dynamics of galaxies are well characterized by their position on the Tully–Fisher relation, which shows that for spiral galaxies the //asymptotic// rotational velocity is uniquely related to their total luminosity. "

Shouldn't it say asymptotic here? 23:50, 4 June 2021 (UTC)~

Describe "dark matter" at first introduction

@TonySt I think a short phrase describing dark matter should be included where it is first mentioned. Something like

dark matter is hypothetical form of matter that has mass but does not interact with light.
