SUMMARY

This discussion centers on Mach's Principle, which posits that for an object to exist, it must continuously interact with the universe. A hypothetical scenario involving a machine that isolates an object raises questions about existence and perception. The conversation highlights the imprecision of Mach's Principle, noting that there are at least 21 interpretations. Additionally, it is clarified that Quantum Mechanics (QM) does not necessitate Mach's Principle, although some interpretations may suggest a connection.

PREREQUISITES
  • Understanding of Mach's Principle and its implications in physics
  • Familiarity with Quantum Mechanics (QM) concepts
  • Knowledge of philosophical discussions surrounding existence and perception
  • Awareness of the historical context of Mach's Principle
NEXT STEPS
  • Research the various interpretations of Mach's Principle
  • Explore Quantum Mechanics interpretations related to existence
  • Study the historical significance of Mach's Principle in physics
  • Investigate philosophical implications of perception and existence
USEFUL FOR

This discussion is beneficial for physicists, philosophers, and students interested in the foundational concepts of existence, perception, and the implications of Mach's Principle in modern physics.

"Imagine a machine which is a box with a door. Place an object in the box, shut the door, and the machine shields all interactions between the object and the universe. When I open the box, what will I see? Will it be the same thing I would see if I had placed nothing in the box before closing the door?
For something to exist it must continually interact with everything else in the universe. This is Mach's principle."

This comment was made in a physics forum , that's true?

Mach's principle is rather imprecise - I read somewhere there are at least 21 versions.

The above however is not one I recall.

Certainly QM does not demand it although some interpretations suggest something along those lines.

Thanks

Bhobba's answer pretty much says it all. This thread is closed, as there is no need to debate claims based on an unacceptable reference. We can usefully discuss the historical significance of Mach's Principle, but that's not this thread.
