Four Ways Scientists See Inside Rocky Exoplanets—and Why None of Them Sees Clearly
Scientists infer the interiors of rocky exoplanets using limited data like mass and radius, facing a core challenge of parameter degeneracy where different compositions yield identical measurements. This article compares mass-radius relationships, Bayesian inference, and machine learning models, explaining why none provide a definitive view.
