Even our most successful and advanced theories of foundational physics – general relativity and quantum theory – have so far been unable to give a complete account of the universe. Meanwhile, philosophy continues to wrestle with questions of knowledge and consciousness. Might constructor theory provide an answer to both?

Constructor theory is a relatively nascent idea in fundamental physics that proposes to underlie all other currently known theories, not to mention those yet to be known, and to solve problems across a host of fields in science and beyond.

Logan Chipkin joins Oxford physicist and constructor theorist Chiara Marletto to discuss what constructor theory is, how it might point the way to a successor to quantum theory, and how it might allow physics to tackle some of philosophy’s most perplexing puzzles.
