I think it's a matter of theory supporting observed data. They point the, "camera" at a bunch of experiments, which generates a ton of data, then it's up to theoretical physicists to explain the results. Once the results of a theory have been explained and then reproduced it stands on solid ground. I'm just speculating, of course. But that is sort of how astronomy works, at the polar opposite end of a similar field.
