I think this is ridiculous. Physics is limited by observation. The AI needs to distinguish our universe from many like it where the differences are not observable with current technology. It's like asking to break no-free-lunch theorems. Much better is to ask it to solve a free millennium problems
Physics is limited by observation but also by interpretation of that data. There are lots of unsolved physics problems that essentially amount to "no human has come up with a model that fits this data" that an AI could potentially solve for us.
