Talk:Wigner surmise

What kind of statement is this?
If I understand correctly, the Wigner surmise is a statement (or pair of statements) about a mathematical model of a physical phenomenon. I'm having trouble placing this statement in a category: Or what? Please help readers like me. Mgnbar (talk) 16:38, 28 April 2024 (UTC)
 * 1) Is it an axiom --- that is, an explicit assumption of the model?
 * 2) Is it a theorem --- that is, a fact that can be proved logically from the assumptions of the model?
 * 3) Is it a conjecture --- that is, something suspected to be (exactly) true but not yet proved from the assumptions of the model?
 * 4) Is it an approximation --- that is, a useful (or historically interesting) simplification that isn't exactly true in the context of the model?
