SUMMARY

The discussion centers on whether the collapse of a particle system is influenced by mass, momentum, or complexity. Participants clarify that standard quantum mechanics (QM) does not support the concept of collapse in the way the original poster (OP) suggests. Wojciech Zurek's theory on decoherence time is mentioned, emphasizing that decoherence does not equate to collapse. The need for the OP to refine their question regarding the relationship between the Schrödinger wave function collapse and the properties of macroscopic objects is highlighted.

PREREQUISITES
  • Understanding of standard quantum mechanics (QM)
  • Familiarity with Wojciech Zurek's theory of decoherence
  • Knowledge of the Schrödinger wave function
  • Concept of macroscopic quantum systems
NEXT STEPS
  • Research the implications of decoherence in quantum mechanics
  • Explore the relationship between mass and the behavior of quantum systems
  • Investigate interpretations of quantum mechanics regarding wave function collapse
  • Study macroscopic quantum phenomena and their complexities
USEFUL FOR

Quantum physicists, researchers in quantum mechanics, and students studying the foundations of quantum theory will benefit from this 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.
