Debosmita Sarkar
Independent Physicist & Researcher · Kolkata, India
Debosmita Sarkar is an independent physicist and computational astrophysicist based in Kolkata, India. She is the creator of the Fidelity–Limit Theorem and a provenance-audited gravitational world simulator validated against NASA JPL's DE440 ephemeris.
Known for
- The Fidelity–Limit Theorem — a closed-form predictability horizon for chaotic systems, with the measurement ceiling corollary: beyond a computable point, prediction is limited by how well reality is measured, not by computing power. Learn more →
- A provenance-audited gravitational world simulator — built only from proven physics, validated against NASA JPL DE440, reproducing Mercury's perihelion advance as 42.99″/century (0.03% from the observed value). Learn more →
- Reproducing the ~100-million-year horizon — the theorem independently recovers the established predictability limit of the solar system. Read the paper →
