Is There a Constraint a on the Way Things Go?

Physical law is a constraint on the way things go, but it's not a determinate. It doesn't dictate one thing over another - and we should let physicists develop their theory rather than expect them to do so. But if there are top down influences that mean that microphysical things will behave in ways that physicists wouldn't have expected, then i think we do have reason to bawk at that. Oong: Why aren't there many degrees of freedom left once youv fixed the physical laws? And do we know that that's not the case?
