Time to the collapse

[AndrzejB]

TL;DR Summary

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)

 

[PeterDonis]

decoherence time

Which is not the same thing as "time to collapse", as you note. What do you want to ask about?
