Sensitivity Analysis: JuMBOs Artificial Hypothesis

Key Points

The aim is to refine predictions regarding the JuMBO artificial hypothesis using updated observational data.
Used observational data from 2024-2026 to perform a Bayesian update on the hypothesis posterior.
Identified key parameters like deuterium abundance and binary excess from future data sources.
Outlined decision criteria for validation against specific observational instruments.
Increased hypothesis posterior from a baseline of 14% to a range of 20-28%.
Upper bound of 28% predicted if upcoming data confirms current trends.
Support for ongoing research into JuMBO populations and deuterium measurement.

Abstract

The 2024–2026 observational updates increase the artificial hypothesis posterior by 6–14 percentage points (from 14% baseline to 20–28% current range). The upper bound (28%) is reached if 2026–2027 Roman + ELT data confirm persistent wide-binary excess and deuterium depletion in older field populations.This Bayesian update strengthens the strategic case for: - Continued JuMBO population characterization - Spectroscopic surveys targeting deuterium abundance - Long-baseline astrometric monitoring - Gravitational wave detector sensitivity improvements The framework remains falsifiable via clear 2030 decision criteria tied to specific instruments and observational programs.
