Mass Phase Transition at Relativistic Velocities – A Hypothetical Framework for Energy-Dominated States

This study proposes a theoretical framework called the “Mass Phase Transition Hypothesis,” in which an object’s mass undergoes a transition to a massless, energy-dominated phase as its velocity approaches the speed of light. Inspired by thermodynamic phase transitions, this model suggests that instead of diverging mass, a critical velocity induces a phase boundary, leading to a kinematic redefinition of mass, energy, and momentum.

The hypothesis is mathematically supported using a modified mass function, relativistic energy-momentum relations, and Landau-type free energy potential. This paper includes theoretical derivations, graphical interpretations, and exploratory comparisons to high-energy jet phenomena. It aims to provoke new questions in modern theoretical physics, while remaining consistent with relativistic constraints and observational compatibility.
