Go has a clear objective that you can train for. What would be the objective in coming up with a physics law from raw data? What would it even be training for? That sounds like asking whether DL could create a new board game from a bunch of data on human behavior.

I don't see how it could, and that's kind of how Kant argued against empiricism. You can't derive a conceptual understanding of the world from raw data. There's nothing in raw data to structure or make sense of it without some way to interpret the data. Even calling it data is an interpretive act (as opposed to noise).
