The Time Symmetry in Special Relativity Is Broken?

This paper presents a fundamental revision of the theoretical framework of special relativity by abandoning both the Lorentz transformations and the concept of time dilation. By critically analyzing symmetry issues in relativistic effects, this study argues that time is a universally invariant quantity, remaining unaffected by the relative motion between reference frames. By re-evaluating the core principles of relativity, the study rederives the mass-energy equivalence formula without invoking time dilation or Lorentz transformations. This novel approach resolves long-standing paradoxes in relativity, such as the twin paradox, and opens new possibilities for theoretical and experimental research in fundamental physics.
