Constructor Theory: A New Approach to Physics
The standard way of describing the universe that we've had so far is to try to guess a law that that explains what trajectory the universe is on.
When you kick a ball, you would like to know where it goes, all the points in spacetime that it goes through from start to end.
You'd like to do the same with the universe, and we have some candidates for that.
But there is a problem in setting the initial conditions and also in explaining why some initial conditions as opposed to others.
Constructor theory has a completely different approach to explaining physics.
Instead of talking about laws of motion, trajectories, and things like that, the main statements of constructor theory are about what transformations are possible or impossible on a particular subset of systems of the
universe.
An example that we already know about would be the conservation of energy, but constructor theory adds additional constraints.
From those constraints, you construct the dynamical laws that are compatible with that and the initial conditions.
Therefore, those constraints become the explanations for those dynamical laws and initial conditions.
So the traditional logic is inverted.
