A Consistency Test for Kerr Black Holes via Orbital Motion, Ringdown, and Imaging

Kerr Trisector Closure (KTC) is a consistency test for the Kerr hypothesis that tries to stay honest about what is actually being inferred from data. The guiding principle is simple: if the exterior spacetime of an astrophysical, stationary, uncharged black … Continue reading

Towards a derivation of the metric tensor in general relativity

One of the central tasks in differential geometry is to make precise the notion of length and angle on a smooth manifold. Unlike $\mathbb R^n$, a general manifold comes with no preferred inner product. The metric tensor is not something … Continue reading

Overdetermined parameter interference in physics

In many areas of physics, a system is described by a small number of fundamental parameters, while the available observations greatly exceed this number. When this occurs, the problem of parameter inference becomes overdetermined. Rather than being a drawback, this … Continue reading

A Long-Term Narrowband Astrophotography Project

This project documents a long-term narrowband astrophotography dataset accumulated over roughly two years and more than thirty imaging sessions, with a total integration time approaching two hundred hours. Data were acquired using a reduced refracting optical system and an SHO narrowband filter set, then calibrated, stacked, and mosaicked to produce a deep composite image. The result reflects incremental data accumulation across multiple observing seasons rather than a single planned campaign. Continue reading

The Kerr Trisector Closure: A project on internal consistency tests of General Relativity

General Relativity describes gravity as the curvature of spacetime. Mass and energy determine this curvature, and physical phenomena such as orbital motion, gravitational radiation, and the propagation of light are governed by the resulting geometry. In this framework gravity is … Continue reading

Spacetime as a Lorentzian Manifold

One of the central tasks in differential geometry is to make precise the notion of length and angle on a smooth manifold. Unlike $\mathbb R^n$, a general manifold comes with no preferred inner product. The metric tensor is not something … Continue reading
