B Does Particle System Collapse Depend on Mass, Momentum, or Complexity?

Click For Summary
The discussion centers on whether the collapse of a particle system is influenced by its mass, momentum, or complexity, particularly in macroscopic objects. Participants clarify that standard quantum mechanics (QM) does not support the concept of collapse in the way the original question suggests. The concept of decoherence is mentioned, with emphasis on its distinction from collapse. There is a call for clarification from the original poster regarding their specific inquiry about the relationship between mass/momentum and the time for wave function collapse. Overall, the conversation highlights the need for a more precise question to facilitate meaningful 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.
 
We often see discussions about what QM and QFT mean, but hardly anything on just how fundamental they are to much of physics. To rectify that, see the following; https://www.cambridge.org/engage/api-gateway/coe/assets/orp/resource/item/66a6a6005101a2ffa86cdd48/original/a-derivation-of-maxwell-s-equations-from-first-principles.pdf 'Somewhat magically, if one then applies local gauge invariance to the Dirac Lagrangian, a field appears, and from this field it is possible to derive Maxwell’s...
