Seminar | Tales Rick Perche, Relativistic Causality is non-binary

Common discussions of causality are typically binary: either a party can causally influence another, or it cannot. This binary notion of causality is key in fundamental concepts that shape our understanding of the world, such as Bell's theorem and precise formulations of quantum field theory. In this talk we will discuss that systems that are compatible with this binary notion of causality are an unphysical idealization, implying that a generalization of our current understanding of causality is in place. By challenging the assumption that causality must be binary, we raise questions about whether our current formulations of Bell’s theorem and quantum field theory fully capture the fundamental properties of our universe.
