It is entirely possible that our scientific model of everything departs enormously from how the universe actually works. It could all be total bullshit. But if that's the case, we've slowly dug our way into giant pile of incredibly useful bullshit. Proper application of the scientific method always ensures that you move toward ideas that have useful predictive power and throw out those ideas that don't. It never ensures that you move toward Capital T Truth and it is incredibly unstable in terms of having any sort of lasting certainty about The Way Things Are.
That's tricky in terms of public relations. To properly understand an active scientific field, you have to be willing to consider and mull over ten possibly conflicting ideas at once without getting upset that no one can tell you which one is true.
