What if there were no observers?

Click For Summary
SUMMARY

This discussion centers on the implications of the absence of observers in quantum mechanics (QM). Participants assert that while QM describes interactions and phenomena, it does not necessitate conscious observers for the universe to exist. Key points include that the wave function collapse is merely an interpretation and that physical processes like the Big Bang and star formation occur independently of observation. Ultimately, the consensus is that without any form of measurement, QM as currently understood cannot be operationally defined.

PREREQUISITES
  • Understanding of quantum mechanics principles, including wave function and collapse.
  • Familiarity with the concept of observers in quantum theory.
  • Basic knowledge of cosmology, particularly the Big Bang and nucleosynthesis.
  • Awareness of the philosophical implications of measurement and observation in physics.
NEXT STEPS
  • Research the interpretations of quantum mechanics, focusing on the role of observers.
  • Explore the implications of wave function collapse in various quantum interpretations.
  • Study the relationship between quantum mechanics and general relativity, especially in cosmological contexts.
  • Investigate the philosophical debates surrounding measurement in quantum physics.
USEFUL FOR

Students and enthusiasts of quantum physics, philosophers of science, and researchers exploring the foundational aspects of quantum mechanics and its interpretations.

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.
