MCE Theory

Interactive Simulations

Run the numerical illustrations for MCE v13.0 in your browser. Each simulation executes real Python, NumPy and Matplotlib code through Pyodide (Python compiled to WebAssembly). All computation is local to your device; nothing is sent to a server.

First run: The Python runtime (NumPy and Matplotlib, about 25 MB) downloads once per browser session. Expect 15 to 40 seconds on a typical connection. Later simulations on this page start immediately.

Available Simulations

Environment-Dependent RangeLevel 1 mechanism
Ready
Range of the screened scalar force against ambient density for a chameleon-type potential (n = 1, Λ = 2.4 meV, three couplings). The range is long in a vacuum chamber and short in dense matter. The parameters are a reference choice, not a fit.
Runs entirely in your browser via Pyodide — no server, no timeout.
Composition Dependence and ReachCore prediction
Ready
The isospin coefficient δ(Z,A) for several materials, and the unscreened differential signal 2β₀²Δδ against the MICROSCOPE bound on eta (an Earth-sourced test). Screening and range (the factor f) are not included because they have not been computed, and a near-source signal must also be referred to the source's own pull (main document, Section 3).
Runs entirely in your browser via Pyodide — no server, no timeout.
Flat Disc: Direction of GravityGeometry test
Ready
Plumb-line tilt on a finite flat disc of Earth-like density, using Newtonian gravity from the metric sector (no scalar coupling involved). Compares the result with the measured deflection of the vertical.
Runs entirely in your browser via Pyodide — no server, no timeout.
Foucault Precession and Toroidal QuadrupoleGeometry test
Ready
Left: the latitude dependence of an ideal Foucault pendulum. Right: the quadrupole moment J2 of a uniform torus against the measured value for the Earth.

Technical Notes

  • Inputs: Every number is either a physical constant, a stated benchmark or a value from a cited experiment. No random numbers and no synthetic data are used, so results are identical on every run.
  • Status of the physics: The first two simulations illustrate the Level 1 screened scalar sector, whose parameters are free. See Screened Scalar Sector. The last two reproduce the calculations in Global Geometry Hypothesis Tests.
  • Standalone script: scripts/global_geometry_tests.py runs the geometry calculations from the command line with only a standard Python installation.
  • Legacy scripts: The other files in scripts/ implement the v12 model that the audit withdrew. They are kept for the record and are no longer shown here.
  • Figure download: Use the "Download figure" link beneath each plot to save a PNG.
