This paper introduces the idea of Cosmic Resource Inequality: the possibility that different planetary systems are born with different amounts and types of useful elements and isotopes. These inherited materials may affect how planets evolve and what kinds of technologies a civilization can develop. For example, systems with more radiogenic elements such as uranium, thorium, and potassium may have different internal heating, geology, and long-term habitability than systems with fewer of them. The paper also proposes the Material Potential Scale (MPS), a framework inspired by the Kardashev Scale. Instead of measuring civilizations only by energy use, the MPS looks at the material resources available in a solar system, including heavy elements, volatile compounds, metals, and possible rare isotopes. The goal is not to claim that materials alone determine civilization, but to suggest that a civilization’s technological path may be partly shaped by the “cosmic toolbox” its solar system inherited.
