Rishav Jha

Independent researcher, Mumbai. Quantum decoherence in extreme gravitational fields — built without a lab, without institutional support.

Before measurement

I was sixteen, replaying the Gargantua scene from Interstellar in my head, when the question landed: if a person fell into that black hole, what happens to the information that made them them? No lab, no institutional support. I started investigating anyway.

That question turned into a running investigation of how decoherence behaves across different black hole geometries — Schwarzschild first, then Reissner-Nordström, then Kerr-Newman. A conjecture from that work is headed to the St. Yau High School Science Award. Next: integrating thermal engineering principles to study black hole thermal decoherence directly.

I'm a first-generation researcher from Narsipada, Kandivali East, Mumbai. My father is a labour contractor; my mother is a homemaker. When I found a counting error in my own published data, I corrected it publicly, dropping my effect size from 2.67 to 1.80, because the work has to survive contact with scrutiny.

The work, while it's still uncertain

Quantum Decoherence in Reissner-Nordström Spacetime

A phenomenological computational framework for decoherence near charged black holes — four independent channels (thermal, gravitational tidal, vacuum fluctuation, electromagnetic), built entirely in HTML5/JS with no lab access. Validated empirically: n=27, 39.3 percentage point learning gain, Cohen's d = 1.80, p < 0.001.

Superposition — a narrative physics game

An interactive Three.js/React game where the player falls into a near-extremal Kerr-Newman black hole as a quantum state. Puzzles include surface-code error correction, Page curve identification, and spin-parameter tuning, grounded in original research on electromagnetic decoherence suppression. Built solo for Hack Club Stardance.

Primes as locally logarithmically minimal integers

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

The question

Replaying the Gargantua scene from Interstellar, the question lands: if a person fell into a black hole, what happens to the information that made them them. No lab, no plan — just the question.

August – November 2025

Working on it

The question turns into a real investigation — Schwarzschild first, then deeper. Long, mostly invisible months of building a decoherence framework from scratch in a browser, with no institutional access.

November 2025

Number theory, on the side

Notices that primes consistently saturate to unity after a fixed number of repeated square-root operations on a basic calculator, composites a step later — the start of what becomes the locally logarithmically minimal integers paper.
