at the end, where it says:
"Newtonian notion of time essentially carries over to special relativistic systems, hidden in the spacetime structure."
it is referring to the Causal structure of spacetime.
I've added the expert-subject template. This article has some interesting ideas in it, but some of it is wrong, and a lot of it reads like an attempt by someone without deep expertise to summarize half-understood stuff that they've read.-- 76.169.116.244 ( talk) 03:59, 22 May 2015 (UTC)
The article currently has this: "The theory that combines general relativity and quantum mechanics, Many worlds interpretation is called Wheeler–DeWitt equation. Wheeler–DeWitt equation says there is no time at all." This is total nonsense in technical terms, as well as being ungrammatical. The MWI has nothing to do with general relativity, nor does it "say there is no time." I'll delete this, but it's just the most egregious example of the poor quality of the article.-- 76.169.116.244 ( talk) 04:02, 22 May 2015 (UTC)
[1]"The only way to reconcile all the observations, Cotler says, is to conclude that the photon went through multiple histories in parallel."
So the reality may be against the Copenhagen interpretation and concept of consistent histories... Kartasto ( talk) 11:42, 10 April 2016 (UTC)
Is there scope for an article describing the conflicts/incompatibilities between general relativity and quantum mechanics, linking to this subject, and anything else, along with links to all the theories trying to merge/reconcile differences . This would be an overview, but could potentially be a place to provide more detail on this Fmadd ( talk) 13:47, 30 January 2017 (UTC)
I am not an expert but this looks awfully like OR / someone's pet opinion William M. Connolley ( talk) 10:13, 30 January 2018 (UTC)
"It also involves the related question of why time seems to flow in a single direction, despite the fact that no known physical laws at the microscopic level seem to require a single direction. For macroscopic systems the directionality of time is directly linked to first principles such as the second law of thermodynamics."
This is plain incorrect. There is a related "problem"/open question in physics under the name "the arrow of time", but both QM and GR are agnostic with respect to time reversal. Kilgore T ( talk) 03:09, 2 July 2022 (UTC)
