Discussion Overview
The discussion revolves around the concept of time in quantum mechanics, specifically exploring whether there exists a framework or interpretation of quantum mechanics that operates without the notion of time. Participants engage with the implications of such a view and its motivations.
Discussion Character
- Debate/contested
Main Points Raised
- One participant questions the existence of a view in quantum mechanics that does not incorporate time as a concept.
- Another participant asserts that there is no such view, suggesting that even those who argue for the non-existence of time at a fundamental level still account for its emergence at an effective level.
- A participant expresses curiosity about the motivation behind the initial question and considers how timelessness might provide explanations for phenomena like retrocausality.
- Another participant mentions that their thoughts on timelessness are not fully developed and acknowledges the speculative nature of their ideas.
- One participant challenges the relevance of retrocausality in physics, suggesting it is unnecessary to consider quantum theory without time.
- A participant recalls hearing about quantum mechanics theories that lack a time component but questions the validity of such claims, ultimately expressing skepticism about the idea.
- A later reply requests specific references for claims made about quantum mechanics theories without time, emphasizing the need for concrete evidence.
Areas of Agreement / Disagreement
Participants exhibit disagreement regarding the existence and relevance of quantum mechanics interpretations without time. Some express skepticism about the feasibility of such views, while others explore the implications of timelessness.
Contextual Notes
Some participants acknowledge the speculative nature of their ideas and the lack of concrete references for claims made, indicating limitations in the discussion.

Indeed, even those who claim that time does not exist at the fundamental level, still try to explain how effective time emerges at an effective level.

Why? Just asking about the motivation of the question.entropy1 said:

I am thinking some things over in which timelessness could explain some things. For example retrocausality.martinbn said:

Yes, I can't tell you much because they are not purely physics nor is it decently worked out. Kind'a crackpot.martinbn said:
But everyone many thanks for answering!

Since there is no retrocausality in physics (neither in classical nor quantum) your don't need to bother to think about QT without time.

I heard somewhere sometime that some QM theories have no time. But now I think of it, that seems a bit silly because it obviously does exist in some way.

This is not a valid reference. Please give a specific link to a specific reference. If you don't have one, then please refrain from making such vague references in the first place.entropy1 said:
