A Spiral Structure in the Inner Oort Cloud: A Simulation Reveals Unexpected Findings

2025-06-05

New simulations reveal an unexpected spiral structure within the inner Oort cloud of our solar system. Researchers used high-resolution simulations to track millions of small bodies whose motions are influenced by both planetary scattering and galactic tides. The results show that the inner Oort cloud is not uniformly distributed, but rather a warped disk exhibiting two spiral arms, a direct consequence of Kozai cycles induced by galactic tides. This discovery offers new insights into the formation and evolution of the Oort cloud and provides new targets for future observations.

Nonlinear Generalization of Maxwell's Equations from a Variational Approach

2025-04-20

This research article derives a nonlinear generalization of Maxwell's equations from a variational approach where the action measures the variability of the metric tensor. The space is a Weyl space where the metric tensor's covariant derivative needn't vanish. The Lorentz force law is derived as a geodesic equation. Charge density obeys a covariant wave equation, suggesting it's a field propagating at light speed, supporting the wave nature of electrons. The Dirac equation is also shown to be geometric. The link between the Lorentz force and spacetime's metric directly explains Zitterbewegung and quantum mechanical waves.
