Science is about maps. Technology is about using those maps. No map allows you to control, just to understand.

Briefly, an ultimate map of science may exist if reality is based on a finite number of rules. We wouldn't be 'understanding' the universe but we would be identifying the rules that generate or unfold into our universe. Finite rules can lead to infinite constructs (E.G. the rule 'add 1').

What I said was science suggests that rules are the key. You mentioned something about 'quantum foam' and virtual particles in one of your articles. Such things need to exist in (empty) space-time. The 'rules' of quantum mechanics can create 'space-time' from no-'space-time' which is a deeper level of nothing. Rules therefore are the foundation.

The question then is where do rules come from? The answer is no rules which is equivalent to any rule applies. ‘Our’ reality, the physical world, may then be a subset or bubble of one or a few rules. If so, the ultimate theory is just to identify this one or a few rules which generated the universe we belong to. Why those rules? Because they generate the universe. Why do those rules exist? Because no rules exist and thus all rules exist and some rules may form their own ‘bubbles’ of reality. There is no need for further ‘explanation’ of the rules because all the rules go. We just happen to be in the one that unfolds into the universe we exist in. There are no turtles all the way down.
