\begin{abstract}
Both the \textbf{Timeless Light Model (TLM)} and the historical \textbf{Wheeler--Feynman absorber theory (WFAT)} link emission to absorption.
Yet the resemblance is only superficial. WFAT (1945--49) relied on advanced and retarded waves and a universal absorber, an elegant construction that was ultimately abandoned.
TLM, by contrast, is a modern ontological framework built on the \emph{Generalized Pairing Law}, stripped of advanced waves and untestable global boundary conditions.
This paper disambiguates the two, showing how they share a family resemblance but diverge in scope, mechanism, and falsifiability.
\end{abstract}
\section{Wheeler--Feynman Absorber Theory (WFAT)}
In WFAT \citep{wheeler1945,feynman1949}, an accelerating charge emits both retarded (forward in time) and advanced (backward in time) waves.
Absorbers in the universe respond with advanced waves that cancel the emitter’s own advanced part, leaving only the retarded radiation we observe.
The goal was to eliminate self-interaction infinities in classical electrodynamics.
Problems that led to abandonment:
\begin{itemize}
\item \textbf{Advanced waves}: backward-in-time solutions violate causality if taken literally.
\item \textbf{Universal absorber}: theory required the entire universe to act as a perfect absorber, untestable as a boundary condition.
\item \textbf{Quantum incompatibility}: with the rise of renormalized QED, WFAT lost relevance and was set aside.
\end{itemize}
\section{The Timeless Light Model (TLM)}
By contrast, TLM emerges from a sequence of axioms and simplifications:
\begin{itemize}
\item \textbf{Generalized Pairing Law (GPL)}: No quantum emission occurs without an absorber \citep{McKinley2025Pairing}. Includes a photon-specific clause forbidding orphan photons.
\item \textbf{Quanta Transfer Law}: Quanta as synchronous state transfers, not travelers \citep{McKinley2025Transfer}.
\item \textbf{Binary Law of Quanta}: emission/absorption as a 0/1 toggle \citep{McKinley2025Binary}.
\item \textbf{Unified Quantization Principle}: GR, SR, and QM as quantized deployments of binary quanta \citep{McKinley2025Unified}.
\item \textbf{Quanta Global / Frames Local}: quanta are timeless, frames are local renderings \citep{McKinley2025Rosetta}.
\item \textbf{Two Decrees}: Charge-YES and Frame-YES suffice to generate the Standard Model within TLM \citep{McKinley2025TwoDecrees}.
\item \textbf{TLM Addendum}: minimal formalism and a decisive null test \citep{McKinley2025Addendum}.
\end{itemize}
Unlike WFAT, TLM assumes no advanced waves, no global absorber, and is explicitly falsifiable: any confirmed detection of an orphan quantum would refute it.
This falsifiability is exemplified by the A/B null test in the Addendum for remote absorber effects.
\section{Disambiguation}
Though both theories link emission to absorption, the differences are decisive:
\begin{itemize}
\item \textbf{Scope}: WFAT limited to photons in electrodynamics; TLM applies to all quanta.
\item \textbf{Mechanism}: WFAT uses advanced/retarded interference and universal absorber; TLM posits direct ontological pairing without fields propagating backward in time.
\item \textbf{Complexity}: WFAT is mathematically intricate, historically abandoned; TLM is deliberately simple and falsifiable.
\item \textbf{Programmatic integration}: WFAT stood alone; TLM integrates into a coherent sequence (GPL $\rightarrow$ Transfer $\rightarrow$ Binary $\rightarrow$ UQP $\rightarrow$ Rosetta $\rightarrow$ Decrees $\rightarrow$ Addendum).
\end{itemize}
\section{Conclusion}
The Timeless Light Model and the Wheeler--Feynman absorber theory share a superficial family resemblance: both tie emission to absorption.
But WFAT is an abandoned classical construction dependent on advanced waves and global boundary assumptions.
TLM is a modern framework built on falsifiable axioms, extending beyond photons to all quanta, and integrated into a unified ontology of physics.
Thus, while WFAT is a historical curiosity, TLM is positioned as a viable modern program.
The 80-year gap underscores WFAT’s status as an abandoned mid-20th century idea, while TLM represents an active 2025 program with defined empirical tests. WFAT is history; TLM is testable physics.
