Python Constructor Theory Simulator: Quantum Gravity & Electromagnetism in Code

A Python implementation of David Deutsch's Constructor Theory framework, showcasing core concepts—from simple Tasks and branching substrates to quantum gravity and electromagnetism—entirely in code. It includes a "universal constructor" capable of bootstrapping itself from a list of Tasks, demonstrating self-replication and the power of Constructor Theory. Features include irreversible & quantum tasks, timers & clocks, fungibility, continuous dynamics, and coupling tasks like gravitational two-body, Coulomb coupling, and Lorentz force.
