Whereas with nuclear decay what you call 'cause' is just being the thing, eg an atom of an unstable isotope. | |

| Oct 31, 2023 at 7:11 | comment | added | Conifold | I do not think spontaneous means "does not have a cause" or anything like "voluntary". Physicists do call a form of decay spontaneous fission, they also have spontaneous emission, spontaneous symmetry breaking, etc. And voluntary actions are not entirely uncaused either, there are physical constraints and motives involved. There isn't much difference with partial causes of quantum events, collapse is an analog of "decision". | |
