Science cannot explain the nature of reality itself. Anything it can explain and test, is within reality itself. This is because at the heart of science are tests, which are meant to predict how reality unfolds. In other words, without reality "unfolding" (whatever that may be), you can't test anything and therefore you can't practice science. We've already bumped into this with Quantum Theory. Experiments can't solve 'the measurement problem', and interpretations like 'Many Worlds' where multiple parallel universes exist, are unfalsifiable and untestable. I think the Big Bang falls into this as well, since we have no idea what exists before time started.
