What if there were no observers?

Click For Summary

Discussion Overview

The discussion revolves around the implications of the absence of observers in quantum mechanics (QM). Participants explore theoretical scenarios regarding measurement, the nature of existence, and the role of observers in the context of quantum phenomena, touching on both conceptual and interpretative aspects of QM.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that without observers, the wave function would never collapse, indicating a fundamental aspect of QM that relies on observation.
  • Others argue that QM can describe the laws of nature without conscious observers, pointing out that the early universe existed without conscious life.
  • A participant questions the definition of a physical process and whether all measurements qualify as such.
  • There is a discussion about the implications of having no observers, with some suggesting that it would lead to uncertainty, while others assert that the universe would not exist at all without some form of interaction.
  • Some participants highlight that the term "observer" in QM is complex and can refer to any interaction that yields a result, not just conscious observation.
  • One viewpoint suggests that the concept of observers must be contextualized within macroscopic systems, as QM may not be operationally defined without them.
  • There is a mention of the Big Bang and its relation to the discussion, with differing opinions on whether it can be considered an observer-less event.
  • A participant emphasizes the importance of experimenters in conducting experiments, suggesting that their decisions and actions are crucial to the experimental process.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the role of observers in QM. There is no consensus on whether the absence of observers would lead to a meaningful interpretation of quantum mechanics or if it would imply a lack of existence or measurement altogether.

Contextual Notes

Some discussions hinge on the definitions of observers and physical processes, as well as the implications of quantum mechanics without a macroscopic context. The complexity of these definitions and their interpretations remains unresolved.

I see… I think I’m gonna lock the thread here since that’s probably the case. An “observer” is kind of an undefined thing where it can vary from person to person, so I suppose I had a wrong understanding on what it is. Still, thanks a lot for explaining all of this to me!

Best regards,

(oh right how do i lock it i actually don’t know)

You don't. You ask a moderator, like me, to lock it. :wink:

I have now done so. Thanks to all who participated in the thread.
