In fact, Deutsch claims that constructor theory forms a kind of bedrock of reality from which all the laws of physics emerge.<br /><br />Constructor theory is a radically different way of thinking about the universe that Deutsch has been developing for some time. He points out that physicists currently ply their trade by explaining the world in terms of initial conditions and laws of motion. This leads to a distinction between what happens and what does not happen.<br /><br />Constructor theory turns this approach on its head. Deutsch’s new fundamental principle is that all laws of physics are expressible entirely in terms of the physical transformations that are possible and those that are impossible.<br /><b>In other words, the laws of physics do not tell you what is possible and impossible, they are the result of what is possible and impossible</b>. So reasoning about the physical transformations that are possible and impossible leads to the laws of physics.<br /><br />That’s why constructor theory is deeper than anything that has gone before it. In fact, Deutsch does not think about it as a law of physics but as a principle, or set of principles, that the laws of physics must obey.<br />The analogy that he draws is with conservation laws such as the conservation of energy. This is not a law of physics like quantum mechanics or relativity but a principle that all other laws must follow. As energy is converted from chemical to electrical to kinetic to potential energy and so on, its behaviour is governed by all kinds of different laws of physics. But they must all obey the principle that energy is conserved.<br /><br />“Thus the conservation law, though not an a priori mathematical truth, provides an explanation of aspects of motion that is deeper than laws of motion,” say Deutsch and Marletto.<br />Constructor theory plays a similar role. “It is a principle, namely a law of physics that expresses and explains constraints on other laws rather than on the behaviour of physical objects directly,” they say. It is the one law to rule them all, (as…errr…Tolkien might have put it). </i><br /><br />Vezi Mirel?
