Provides a non-technical overview of causal fermion systems

Shows how the theory encompasses quantum mechanics and general relativity

Suggests potential for unification of fundamental physics

Abstract

The theory of causal fermion systems is an approach to describe fundamental physics. Giving quantum mechanics, general relativity and quantum field theory as limiting cases, it is a candidate for a unified physical theory. We here give a non-technical introduction.
