If we say that science and technology is a way to manipulate matter in the course of a timespan on a 'higher layer', what implications would this have? We define a higher layer as a way of programming, for instance in the programming language C, you have to do 'low level' managment of memory and so forth, while in Perl, you don't need to do this. And on the lowest level is actually binary numbers, just 0 and 1, or so called machine code. Level equals layer in this analogy. Now assuming that the universe has some kind of fundamental or primordial entity, if we say that an object in the world has a total amount of mass 100%, then we can say that with science, we can manipulate only 50% of the matter, because we're not controlling the quantum mechanics, or the strings, or even on a molecular level. Once we learn how to control all of these things, down to the most fundamental entity, would we then be controlling time too? If time is just an emergent property of mass, then it seems to me we could indeed do pretty much anything that the universe itself can do, only we would consciously do it. If the universe is a deterministic system which unfolds itself based on the rules that are in place, then we should in theory be able to do exactly what the universe is doing and has done ever since its creation once we reach a certain level of knowledge.
