Yes, that's what I mean by "new physics".

Not being snarky, but when would "new physics" just became a "theory"? These ideas aren't all that new.

[Vecr]

I didn't say they can't be theories. I don't think Penrose ever got that far though. There theoretically were some measurements that would distinguish the idea, but since it was attached to quantum gravity the math was never worked out.
