Discussion Overview

The discussion centers around whether the time to collapse of a particle system is influenced primarily by its mass, momentum, or complexity. Participants explore this question in the context of quantum mechanics, particularly regarding macroscopic objects and the implications of isolation on spontaneous collapse.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question the existence of a defined "time to collapse" in standard quantum mechanics (QM) and seek clarification on the specific model or interpretation being referenced.
  • One participant mentions Wojciech Zurek's theory, highlighting the concept of decoherence time, but notes that decoherence does not equate to collapse.
  • Another participant suggests that the original poster (OP) may be inquiring about the influence of mass/momentum or complexity on the "time for the Schrödinger wave function to collapse," indicating a need for clarification on the OP's intent.
  • There is a call for the OP to provide more details rather than reiterating the initial question, as previous points have already raised issues with the assumptions made.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple competing views regarding the interpretation of collapse in quantum mechanics and the relevance of the OP's question.

Contextual Notes

There are unresolved assumptions regarding the definitions of collapse and decoherence, as well as the specific models being referenced in the discussion.

TL;DR
Time to the collapse macroscopic object depends on its mass/momentum or complexity?
Does the time to the collapse of a particle system depend mainly on its mass/momentum, or complexity? For example macroscopic object.
If system is quite isolated, is no spontaneous collapse even massive or complex systems?

time to the collapse
There is no such thing in standard QM. What model or interpretation are you asking about?

For example in Wojciech Zurek theory - decoherence time (although decoherence not means collaps)

decoherence time
Which is not the same thing as "time to collapse", as you note. What do you want to ask about?
 
Perhaps the OP means to ask if the "time for the Shoedinger wave function to collapse" is affected by the "mass/momentum" of a macroscopic object or by its "complexity". @AndrzejB: is this summary appropriate?

(Quote marks because I suspect some of the assumptions made)
 
@DStahl all you have done is repeat the OP question, which has the issues I have already pointed out. We don't need anyone else repeating the OP's question. We need the OP to clarify what they want to ask about.
