GR & QM

Latest comment: 7 years ago1 comment1 person in discussion

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)Reply

OR?

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)Reply

The word "this" seems to refer to the whole article. I agree that time is hard to define. — Preceding unsigned comment added by Gdklrtwb (talk • contribs)

Arrow of time

Latest comment: 2 years ago1 comment1 person in discussion

"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)Reply

"external observers of the Universe"

Latest comment: 30 days ago1 comment1 person in discussion

"They confirmed for photons that time is an emergent phenomenon for internal observers but absent for external observers of the universe just as the Wheeler–DeWitt equation predicts."

The cited articles in Phys Rev A and D refer to some "internal" and "external" observers of a quantum system so it will be better to delete this phrase about the "external observers of the Universe". TV8phys (talk) 21:55, 24 October 2024 (UTC)Reply
