Quantum Mechanics without time?

Click For Summary
SUMMARY

The discussion centers on the concept of time in quantum mechanics, specifically questioning whether a framework exists that excludes time as a fundamental element. Participants agree that while some theories may suggest the absence of time, effective time still emerges in quantum mechanics. The conversation touches on retrocausality, but concludes that it lacks support in established physics, reinforcing the necessity of time in quantum theories.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with retrocausality concepts
  • Knowledge of effective theories in physics
  • Awareness of the philosophical implications of time in physics
NEXT STEPS
  • Research "quantum mechanics and the concept of time"
  • Explore "retrocausality in quantum physics"
  • Investigate "effective field theories in physics"
  • Study "philosophical implications of time in quantum mechanics"
USEFUL FOR

Physicists, philosophers of science, and students of quantum mechanics seeking to understand the role of time in quantum theories and its implications for theoretical frameworks.

Is there a view in quantummechanics, of quantummechanics, without time as a concept?

No.

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.

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

Well, that clarifies somethings about things.

Yes, I can't tell you much because they are not purely physics nor is it decently worked out. Kind'a crackpot. 🤪 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. :oldbiggrin:
 
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.
