What is the Quantum Domain and Its Role in Levels of Existence?

[Satya_Sen]

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?

 

[HomogenousCow]

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:
