- TL;DR Summary
- What does the wavefunction look like if the position is known precisely, but there are so many particles involved such that the certainty in position is high since the mass is much greater than Planck's constant?

I understand that the uncertainty is low when you're dealing with a "macro" scale area that is much bigger than Planck's constant. But what's confusing to me is when you know with extreme precision the location, but there's so many particles involved that there is little uncertainty since the mass involved is so much greater than Planck's constant. For example, let's say there were a bowling ball that had its position measured with extreme accuracy. We wouldn't get hardly any uncertainty in either its position or momentum because its mass is so much greater than Planck's constant, but what does that mean in terms of the wavefunction? And you might say that the bowling ball takes up a lot of space such that my premise is flawed, but what if we throw the bowling ball into a black hole where it's crushed down to size?
