WHAT IS CONSTRUCTOR THEORY?


The basic principle of constructor theory is that all fundamental laws of nature are expressible entirely in terms of statements of which tasks (i.e. classes of physical transformations) are possible and which are impossible, and why. This is a new mode of explanation, intended to supersede the prevailing conception of fundamental physics which seeks to explain the world in terms of its state (describing everything that is there) and laws of motion (describing how the everything changes with time). By regarding counter-factuals ('X is possible' or 'X is impossible') as first-class, exact statements, constructor theory brings all sorts of interesting fields, currently regarded as inherently approximative, potentially into fundamental physics. These include the theories of information, knowledge, thermodynamics, life, and of course the universal constructor.

Oxford University is conducting research into constructor theory and its implications in a project involving David Deutsch, Chiara Marletto and Simon Benjamin. The research is supported by the Templeton World Charity Foundation.

As the project progresses, papers, articles and videos will be made available at this website.
