How Scientists View Quantum PhysicsAccording to physicist Hugh Everett III, what happens is this: When someone makes a measurement of a wave function, they don’t collapse it, they become part of it. According to physicist Hugh Everett III, when someone makes a measurement of a wave function, they don’t collapse it, they become part of it. The criteria of adequacy—fruitfulness, simplicity, scope, conservatism—can be used to delineate between theories that make the same predictions. The non-realist, on the other hand, will say that the predictive power of a theory isn’t a reason to think that it describes reality. If the realists are right, then subatomic particles are waves until they are measured, at which time they collapse down into particles with particular properties. The problem with taking this approach with quantum mechanics, or relativity for that matter, is essentially twofold. Literally, to account for what their observation does, they have to plug themself in as a variable into the quantum wave equation.
