To the Rambam learning Physics and Metaphysics brings to fear and love of God which are the major goals of the Torah.
Let me try to be short.
The Torah is clothed in the Creation. So when you learn about God's creation you are learning God's wisdom.
But you could in theory go into this in detail with bringing different places where the Rambam go into this in more detail. This is probably a worthwhile project also since for some reason people tend to go away from physics when they start learning Torah thinking there is some kind of contradiction.
Major sources: Rambam beginning of the Guide, beginning of Mishna Torah, end of vol III or (vol II) in the Guide in the story about the palace of the King,
To put this all together you have to start with the idea that the goal of Torah is to come to love and fear of God. Then you need the idea that the the world was created by the ten statements of Genesis, and thus those statements are the life force of all that is in the world. And that those ten statements are the clothing of the Ten Commandments. And the highest statement is the first one "In the beginning God created heaven and earth" in which it does not say openly God said. It is the hidden statement which is the life force of everything and everywhere where God's glory is hidden.
Thus Torah is God's revealed wisdom and Physics and Metaphysics is his hidden wisdom.
That is the short and simple of it.
There are people that if exposed to straight Torah will not be able to accept it. This explains also how often it is better for people to learn the natural sciences rather than open Torah, because זכה נעשית סם חיים, לא זכה נעשית לו סם מוות. By being exposed to open Torah one can become worse. And in fact this often happens before our very eyes.
Also seeing the wisdom inside ever aspect of creation binds ones soul to the purpose of that individual creation which in it s higher source is close to the purpose of all creation which is God's glory.

Appendix:
1) I want to suggest that this learning should be coupled with regular books of Fear of God. Mainly books from the Middle Ages. The world after the Middle Ages lost a lot of Fear of God and so to be inspired in that direction one needs books from that period. Also Musar books after the Middle Ages have a lot of Kabalah and that tends to side track people from good charter into religious fanaticism.
This is why I think the original Musar Movement of Israel Salanter was based on Medieval books of Fear of God and not books based on Kabalah.
I was in fact in a place once that was following this approach of Israel Salanter (Musar), and the effect was electric. (That was the Mir in Brooklyn, NY.)
