A new interpretation of the Length Contraction and the Fermi Paradox——Toward a Thermodynamic Extension of General Relativity

This paper explores a potential thermodynamic extension of General Relativity, offering a new interpretation of the Length Contraction and the Twin Paradox from an alternative perspective. Under the framework of extended General Relativity, it attempts to explain the Fermi Paradox and the fate of civilizations. In this paper, a conceptual analysis approach is adopted, focusing on revealing theoretical conflicts rather than numerical solutions, thereby exposing the strict boundaries of the applicability of physical laws. Within the framework of the extended General Relativity, this paper primarily explores the following issues through conceptual analysis:1. The applicability boundaries of the mass-energy conservation law;2. The relationship between the mass-energy equation and the mass-energy conservation;3. Potential reasons why advanced civilizations may remain undetectable;4. Extensions and historical development of general covariance.This paper aims to explore a potential avenue for extending general relativity to thermodynamics through conceptual analysis. However, it does not yet constitute a complete theory, and it requires further refinement. The formulae mentioned herein are of a conjectural nature.
