Discrete Causal Theory

Más información sobre el libro

Focusing on causal set theory, the book proposes critical enhancements to address fundamental physics challenges. It emphasizes the significance of spacetime structure beyond general relativity and the standard model, introducing the causal metric hypothesis that prioritizes causal relations. By assuming a fundamental scale, it views smooth spacetime geometry as emergent. The text distinguishes itself by highlighting the relative viewpoint of event pairs and histories, ultimately presenting a dynamical law for quantum spacetime through generalized path summation.
