> Science is empiricism. That is it. It is the idea that a theory about how the world works must be put to the test through experimentation.

It used to be that. Now we have theories such as big bang theory, theory of tectonic plates, climate change modelling being seen as a part of science, even though they were never empirically tested (because it's impossible). Science has really changed since its origins back in Newton times, nowadays we accept much more indirect evidence (vs the consistent results of repeated experiments within the parameter space of the theory we used to rely on earlier) as good enough to accept the theory.
