I believe we already were talking about epistemology. :) Science is a means of obtaining knowledge. About what, though?

I suppose "truth" could mean different things in this context. I should have avoided that loaded term or tightly scoped what I meant by it. I meant science is interested in knowledge about how the universe behaves.

Hopefully that doesn't imply science somehow peeks behind the proverbial curtain to see why things behave as they do. Or answering questions like "what is an electron, really".

For example, science has progressively refined models describing how quantum mechanics behaves that can be used to make predictions. But it in no way offers any explanation for why quantum mechanics is the way that it is or what particles are, really.

Scientific experiments test whether models predict outcomes or not, thus determining if the models need to be further refined or even replaced.

The point is simply that science is the best way humanity has this far devised to learn how the universe works.
