AI discovering new laws of physics and making new scientific discoveries indipendently

Could a good AGI test or in general a significant milestone when AI will be able to indipendently and from start to end discover a new law of physics?
From what I understand, for now, AI has not been able to do so, and can only help researchers to do contained and single tasks within the discovery process.

There is also a case to be made that discovering new laws of physics is alot more creative and significant relatively to simply creating new art. We could also argue that when AI will be able to make new scientific discoveries it will have reached conciousness.

This was a discussion I had with a couple of friends that I wanted to share and continue here on Reddit. Let me know your thoughts, I am interested in discussing!
