\section{Observational Tests and Predictions}
|
|
|
|
\subsection{Near-Term Tests}
|
|
|
|
The spin-tether framework makes specific, falsifiable predictions:
|
|
|
|
\textbf{1. Lunar Laser Ranging (2025-2030)}
|
|
\begin{itemize}
|
|
\item Current precision: 1 mm $\rightarrow$ $\sigma < 7 \times 10^{-15}$ m/s²
|
|
\item Prediction at Earth-Moon distance: $\sigma \approx 10^{-14}$ m/s²
|
|
\item Future 0.1 mm precision will definitively test this
|
|
\end{itemize}
|
|
|
|
\textbf{2. Gaia DR4+ Stellar Clusters}
|
|
\begin{itemize}
|
|
\item Prediction: All clusters show similar excess $\sigma \sim 10^{-11}$ m/s²
|
|
\item Test: Analyze 50+ clusters for mass-independent excess
|
|
\item Falsification: No systematic excess or mass-dependent patterns
|
|
\end{itemize}
|
|
|
|
Recent Gaia data releases \cite{GaiaDR3} have already revolutionized our understanding of stellar dynamics. Future releases will provide even more stringent tests of modified gravity theories.
|
|
|
|
\textbf{3. Binary Pulsar Timing}
|
|
\begin{itemize}
|
|
\item Best candidates: PSR J1909-3744, PSR J0437-4715
|
|
\item Prediction: Timing residuals of order $\Delta t \sim \sigma r/c^2$
|
|
\item SKA-era sensitivity may reach required precision
|
|
\end{itemize}
|
|
|
|
\textbf{4. Wide Binary Stars}
|
|
\begin{itemize}
|
|
\item Systems with $a > 10^4$ AU most sensitive
|
|
\item Prediction: Period deviations $\Delta P/P \sim 10^{-7}$
|
|
\item Requires ~20 year baseline with Gaia astrometry
|
|
\end{itemize}
|
|
|
|
\subsection{Cosmological Constraints}
|
|
|
|
The Cosmicflows-4 analysis \cite{Tully2023,Courtois2023} provides the strongest current constraint:\footnote{Velocity field visualization created using \texttt{data-convert.py} script.}
|
|
\begin{itemize}
|
|
\item Upper limit: $\sigma < 5 \times 10^{-13}$ m/s² at ~10 Mpc scales
|
|
\item This rules out constant universal $\sigma$ at levels needed for galaxy dynamics
|
|
\item Consistent with ``unleashed universe'' at cosmic scales
|
|
\end{itemize}
|
|

\section{Discussion: What We Have Learned}
|
|
|
|
This exploration of treating atoms as 3D spinning balls has yielded several insights:
|
|
|
|
\textbf{1. Universal Atomic Success:} The exact reproduction of Coulomb forces across the periodic table (H to Au) using pure 3D geometry strongly suggests atoms really are balls, not abstract 2D systems.
|
|
|
|
\textbf{2. Quantum Gravity Revealed:} If atoms are 3D balls, then electromagnetic force IS quantum gravity at the atomic scale—the same centripetal binding that holds you to Earth holds electrons to nuclei.
|
|
|
|
\textbf{3. Solar System Precision:} Zero-parameter predictions of all planetary precessions confirm the geometric principle scales up perfectly.
|
|
|
|
\textbf{4. Scale-Dependent Physics:} The transition from successful applications at atomic/planetary scales to failures at galactic scales reveals the importance of scale-dependent physics.
|
|
|
|
\textbf{5. Dark Matter Reality:} Our inability to explain galaxy rotation curves confirms that dark matter (or modified gravity) remains necessary for cosmology. The evidence from gravitational lensing \cite{Clowe2006}, cosmic microwave background \cite{Planck2018}, and large-scale structure formation strongly supports the dark matter paradigm.
|
|
|
|
\subsection{The Core Insight}
|
|
|
|
The core insight—that standing on a 3D spinning atom would provide spacetime references while standing on a 2D atom would not—challenges fundamental assumptions about atomic physics. This simple observation has led us to recognize that electromagnetic force may be quantum gravity in disguise, manifesting at the atomic scale through the geometry of three-dimensional rotation.
|
|
|
|
This perspective resonates with approaches like loop quantum gravity \cite{Thiemann2007}, which also emphasizes the geometric nature of spacetime at quantum scales. However, our framework goes further by suggesting that the familiar forces we observe are all manifestations of the same geometric principle operating at different scales.
|
|
|
|
\subsection{Limitations and Next Steps}
|
|
|
|
We acknowledge several limitations:
|
|
|
|
\begin{enumerate}
|
|
\item The framework requires phenomenological modifications ($\sigma$ function) to fit all observations
|
|
\item Galaxy dynamics remain unexplained without dark matter
|
|
\item The connection to quantum field theory is unclear
|
|
\item Many predictions await sufficiently precise measurements
|
|
\end{enumerate}
|
|
|
|
Future theoretical work should focus on:
|
|
\begin{itemize}
|
|
\item Rigorous quantum mechanical treatment of 3D atomic rotation
|
|
\item Connection to gauge theories and fundamental forces
|
|
\item Possible modifications to atomic physics predictions
|
|
\item Integration with general relativity at all scales
|
|
\end{itemize} |
