Is it possible that no individual star OR individual cell can be sufficiently described because of quantum uncertainty effects that would affect any "object" with electrons (speaking as a biologist; not a physicist).

Also: this is a really great, really stellar thread.

Not sure how electrons enter into it. Quantum Mechanics (QM) isn't limited to electrons. Chemistry is largely focused on electrons, so maybe that's where you were first introduced to QM?
