Investigating quantum decoherence in extreme gravitational fields — built without a lab, without institutional support.

01 — Origin

A question with enough gravity to stay.

At sixteen, replaying the Gargantua scene from Interstellar, I asked: if a person fell into that black hole, what happens to the information that made them them? I started investigating anyway.

That question became an investigation of decoherence across Schwarzschild, Reissner–Nordström, and Kerr–Newman geometries. I’m a first-generation researcher from Narsipada, Kandivali East, Mumbai. When I found a counting error in published data, I corrected it publicly: effect size 2.67 became 1.80. The work must survive scrutiny.

The work, while it’s still uncertain.

01

Quantum Decoherence in Reissner–Nordström Spacetime

A phenomenological computational framework for four decoherence channels near charged black holes: thermal, gravitational tidal, vacuum fluctuation, and electromagnetic. Built in HTML5/JS without lab access; empirically validated with n=27, a 39.3 percentage point learning gain, Cohen’s d = 1.80, p < 0.001.

Primes as locally logarithmically minimal integers

Primes saturate to unity after 37 repeated square-root operations on a basic calculator; composites after 38. Formalized as k* = ⌈log₂(ln N/ε)⌉ and validated across four device architectures. Under review at JHM.
