Exploring the Conceptual Foundations of Special Relativity and the Inertial Speed of Light Theory

This paper offers a structured exploration of the conceptual basis of Special Relativity, beginning with a historical overview that led to its development. This is followed by a description of Einstein’s theory, focusing on its conceptual basis rather than its mathematical formalism. The article then identifies potential conceptual tensions—particularly with how light propagates in moving frames and how relativistic effects manifest. Finally, an alternative interpretation is introduced in the form of the Inertial Speed of Light Theory, which reconsiders the relationship between electromagnetic wave propagation and inertial frames. Intended for physicists, students, and theorists interested in the foundations of relativity, this work encourages renewed discussion on the conceptual understanding of space, time, and the nature of light.
