Begin a comparison with a common question
Show how to compare frameworks through a specific problem, common vocabulary, and explicitly stated standards of success.
REALITY & TIME · EXISTENCE AND THE WORLD WE EXPERIENCE
Comparing accounts of reality
Explore comparing accounts of reality through questions connecting temporal order, change, experience, and the interpretation of reality.
Articles in this collection are being developed. Begin with the existing reading below, or visit the first Reality & Time essays.
14 planned topics in this collection
Newtonian and relational accounts of time
Compare their treatment of duration and change, using the existing historical and comparison resources.
Block-universe and generative-time descriptions
Examine how a completed spacetime description relates to proposals about the production of observable events.
Thermal time and generative time
Introduce the different starting questions and assumptions behind thermal-time proposals and the SMM/DTT programme.
Causal sets and completed records
Compare the role of order and discreteness while identifying what each framework assumes about elements and causal relations.
Relational quantum accounts and observer records
Compare the role of relational information without equating distinct formalisms or interpretations.
Process philosophy and DTT
Define the conceptual overlap and the additional mathematical and empirical requirements of a physical research programme.
Information-based reconstructions and completion
Compare operational axioms, retained distinctions, and the task of reconstructing a physical state space.
Different approaches to emergent spacetime
Provide a question-led map of selected approaches and their different mathematical objects, assumptions, and physical targets.
Different meanings of complex time
Distinguish analytic continuation, mathematical parametrization, and proposed physical temporal roles.
Comparing uses of the observer
Separate epistemic agents, reference frames, detectors, and physical subsystems across different approaches.
Unity in metaphysics and unification in physics
Explain the different standards of explanation involved in metaphysical unity and a unified physical dynamics.
Agreement without identity between theories
Show why matching a formula or prediction does not establish that two frameworks have the same content.
How a comparison can suggest new research
Turn a specific difference between frameworks into a proposed calculation, counterexample, or discriminating observation.
