existence?
editWhat is meant with "existence" in the intro? At first sight the use of that word is in conflict with the topic, as absolute space was assumed in Newtonian mechanics to *exist* but impossible to measure directly. Nothing prohibits the same for simultaneity, contrary to the (unreferenced) claim in the article. Harald88 (talk) 16:06, 25 August 2008 (UTC)
Implicature of SR simultaneity
edit"The theory of relativity does not allow the existence of absolute time because of nonexistence of absolute simultaneity." should be something like "SR does not assign a coherent physical meaning to absolute universal time." It should also make clear that other well known qualification about the state of Physics ATM and the SM-GR-SR situation in particular. 72.228.177.92 (talk) 06:09, 24 February 2010 (UTC)
Relative Time & Space
editSince the Grand Narrative of the article is the replacement of absolute concepts with relative ones, is the title appopriate? Should it be called something like Absolute and Relative Space and Time? 1Z (talk) 13:56, 30 December 2010 (UTC)
Combination of Metaphysical and Physical concepts of Absolute spacetime.
editAs outlined in [1], the philosophical and physical concepts of absolute space are different, indeed, in [2] it is noted that in the philosophical sense, modern physics subscribes to absolute space, even if it is relational in the scientific sense. Might it be better to split this article into two?

Contradiction?
editThe opening section contains these statements: "Unlike relative time, Newton believed absolute time was imperceptible and could only be understood mathematically. According to Newton, humans are only capable of perceiving absolute time, which is a measurement of perceivable objects in motion (like the moon or sun)."
So...absolute time is imperceptible, AND humans are only capable of perceiving absolute time...??? Maybe a scientist can explain this better, because it doesn't make sense to me. Xaxafrad (talk) 08:31, 10 September 2013 (UTC)
The section on Einstein's later views does not introduce the aether topic sufficiently, nor explain why this is significant to the topic. A reader may wonder what the aether (ether) is and why it pertains to this topic. The quotes are excessively lengthy and are not introduced, which effect is exaggerated since the preamble lacks detail. How were Einstein's (changing) views on aether important in the development of the ideas of absolute time and space? I would remove this section until a suitable alternative is written. — Preceding unsigned comment added by 209.217.122.179 (talk) 20:35, 7 January 2014 (UTC)
Einstein aether/ether
edit@DVdm: I think we perhaps disagree about whether Luminiferous aether is a suitable link for Einstein's concept, but I'm willing to grant that it properly refers to the concept which Einstein replaced. —jmcgnh(talk) (contribs) 18:29, 15 July 2016 (UTC)
- Of course not for Einstein's "own" concept, but in the section context, it's all we have indeed. - DVdm (talk) 18:35, 15 July 2016 (UTC)

Absolute space in relation to the distant stars
editThe last section states "There appears to be absolute space in relation to the distant stars", which of course is self-contradictory. Motion in relation to the distant stars is by definition relative motion, not anything absolute. 1.75.6.11 (talk) 21:38, 3 September 2017 (UTC)
