I'm not sure how science can expect to answer questions of the form "What is really happening when... ?", since that is entirely unknowable.

Science looks at results and provides useful models. Whether those models are representations of the 'real', or whether the entire universe is actually a bunch of magic pixies who just happen to arrange the universe to look as if it follows a particular theory, or whether the whole thing is a simulation embedded in the real universe which is entirely different are questions not actually accessible to science.
