B Objective-collapse theory, collapse for large objects

Click For Summary
Objective-collapse theory suggests that larger objects, such as a chair, experience wave function collapse differently than microscopic particles. The theory posits that the wave of the chair collapses into a definite position, but the collapse may occur more slowly than for smaller particles, allowing it to remain in a collapsed state longer. This raises questions about the nature of observation and measurement in quantum mechanics, particularly how it applies to macroscopic objects. The discussion highlights the implications of this theory on our understanding of reality at different scales. Overall, the theory challenges traditional views of quantum mechanics by suggesting a distinct behavior for large objects compared to microscopic ones.

TL;DR
Large objects constantly collapsing or remaining collapsed longer?
Let's say we have a big object like chair. According to Objective-collapse theory, is the wave of the chair collapsing and spreading out so fast we see it in one definite position or, does the chair collapse and it remains in this collapsed state longer than microscopic objects like atoms?

Thread 'Angular Momentum Vector and Its Magnitude'

For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
