A periodic sequence can be described using B-relations even though a display returns to the same value. McTaggart’s distinction helps reveal why recurrence of a property is not recurrence of the same temporal position. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

Presentism can describe a succession of recurring presents, while a growing block can contain many distinct repetitions of a similar event. Neither position requires the entire universe to return to an earlier state. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

A block may contain periodic trajectories, quasiperiodic motion or a universe with no exact recurrence. Eternalism does not decide among them. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

A modular flow can have periodic behavior in finite examples when the relevant spectral differences are commensurate, but a generic flow need not close. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

Preselection and postselection can select a system that returns to its initial state, but the laboratory record of the return makes the whole experiment historically different from its beginning. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

Whitehead’s process philosophy allows recurring patterns across different occasions without making the occasions numerically identical. This is close to DTT’s idea that renewed generation can sustain a stable world. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

McTaggart’s challenge is sharpest when the present is treated as a property that moves from event to event. DTT can offer a different formulation: a present is the completion through which a previously unavailable relation becomes accessible. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

DTT’s becoming world is close in spirit to theories that distinguish a real present from an unreal future, but presentism and the growing block diverge over completed history. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

An eternalist can explain why every observer experiences a local now by locating the observer’s state within a complete history. DTT asks whether that explanation omits the production of the state itself. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

Thermal time provides a state-dependent flow, but a flow does not by itself select a privileged present. Every value of its parameter can label an event without one value being ontologically special. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

The two-state formalism describes an intermediate quantum situation in relation to both boundaries, whereas DTT’s becoming concerns how an event acquires completed accessibility. The comparison develops this distinction through a worked example and explains its implications for SMM/DTT’s nested generation, completed records and account of the observable world.

Whitehead’s satisfaction of an occasion and DTT’s outer completion both give achieved actuality a role in subsequent becoming. This is a deep conceptual affinity: the present is not merely a point sliding along an otherwise complete line, but an achievement with inherited content and future relevance. A worked example clarifies the distinction and its implications for SMM/DTT’s account of generation and completed observation.

C061Vacuum and cosmology
A physical vacuum already contains a state, observables and dynamical structure. Comparing SMM/DTT with quantum field theory vacuum, this article asks how one nonspatial source might generate those ingredients, uses a ground-state oscillator as a precise benchmark, and identifies the extra map required to turn source records into a spatial field vacuum.

Vacuum fluctuations, boundary forces and absolute gravitational energy are related but distinct questions. This comparison with quantum field theory vacuum calculates the ideal Casimir pressure, explains what that force measures, and examines how a finite DTT source scale could acquire physical meaning without mistaking a regulator or an energy convention for a prediction.
