Discussion Overview

The discussion centers around the concept of the "Quantum Domain" and its proposed role as a level of existence. Participants explore the implications of quantum effects in both microscopic and macroscopic phenomena, as well as the classification of existence related to quantum mechanics.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that all systems are fundamentally quantum in nature, with quantum effects becoming negligible at larger scales.
  • Others propose that many macroscopic phenomena can only be explained through quantum effects.
  • There is mention of the "Quantum Domain" being described as an "energy soup" that consists of energy and information, although the specifics of this concept are not fully elaborated.
  • One participant emphasizes the importance of citing sources when discussing these topics and provides links to additional resources on decoherence and perspectives from physicists like Weinberg.

Areas of Agreement / Disagreement

Participants express varying interpretations of the Quantum Domain and its implications, indicating that multiple competing views remain without a consensus on its classification or role in existence.

Contextual Notes

Some claims depend on specific definitions of "quantum nature" and "levels of existence," which are not universally agreed upon. The discussion also touches on the concept of decoherence, which remains a complex and nuanced topic.

What is 'Quantum Domain'? I read something about it being a level of existence... If it is a level of existence, what sort of classification of existence are we talking about?

In reality all systems are of a quantum nature, it is simply that quantum effects are negligible at many scales.
However, many macroscopic phenomena can only explained by quantum effects.

Please elaborate a bit more?
I even read something about it being an "energy soup" consisting of energy and information.
Please explain the whole thing and the other levels of existence.

Please get into the habit of citing your sources in full, especially when you are basing your question from it.

These days it is known everything is quantum, but due to interaction with the environment the classical world emerges. This is the decoherence view:

Also what Wienberg has to say will most likely interest you:
