`The Lense-Thirring effect, a prediction of general relativity, implies that massive rotating objects like Earth can slightly "drag" spacetime, which could affect the pendulum's oscillation. This effect, though theoretically significant, is currently too small to measure with a Foucault pendulum.`

Celestial Holography explores one of theoretical physics' most ambitious ideas: encoding our four-dimensional universe as a two-dimensional hologram on the celestial sphere. This deep dive examines how infinite symmetries in gravity, discovered in the 1960s, point toward a radical reorganization of spacetime itself—suggesting the night sky might be where reality's fundamental information is written.
GR vs MOND - not competing theories, both emerge from 7D geometry.
New paper: Kaluza-Klein reduction splits into GR (metric) + MOND (scalar sector).
7D Einstein-Hilbert → Einstein's equations + AQUAL.
Prediction: lensing = dynamics. Testable.

We show that General Relativity and MOND emerge from the same 7D geometric framework through Kaluza-Klein reduction. The 7D Einstein-Hilbert action reduces to: (1) 4D Einstein-Hilbert (GR), (2) scalar moduli, and (3) cross-coupling terms that produce the AQUAL Lagrangian L ~ X^(3/2). GR and MOND are not competing theories but different sectors of 7D geometry---GR governs metric perturbations while MOND governs the scalar sector. The framework predicts that gravitational lensing equals dynamics (no anisotropic stress), resolving a key constraint on relativistic MOND theories.
#Earth's r_jf is approximately 1.5 light-days, leading to #generalrelativity 's successful prediction that all the #frogs in the #SolarSystem should be found collected on the surface of the Earth.
