Supporting Concepts for Understanding Time

Abstract

Grable DR

Understanding the nature of time requires more than philosophy and geometry. Past, present, and future are defined through event sequences and state transitions. Communication and the construction of geometry are key elements for constructing time. Special and general relativity bring together the effects of communication and geometry in understanding time. Quantum theory and particle-to-force relationships underscore the need for precise definitions of time. Time and information flow are inextricably entangled. Significant challenges lie ahead for physics, time, and information science.
