Over the past decades and more recently, there has been a significant effort and renewed interest in<br>extending special relativity theory beyond the speed of light. In this comprehensive note, the paper “Relativity<br>of superluminal observers in 1+3 spacetime” by Dragan et al. [1] is examined. The authors attempted to<br>extend the aforementioned theory to superluminal inertial reference frames by generalizing Parker’s twodimensional transformation with the addition of two pairs of spatial dimensions. This approach is not novel<br>and is already well-documented in the literature. It is demonstrated that unlike Lorentz transformations, the<br>authors’ transformations do not form an orthogonal-orthochronous group due to their negative determinant.<br>Consequently, principles such as relativity, causality, spatial isotropy, and temporal ordering cannot be<br>preserved. The authors’pseudo-transformations are revealed to be reflections in a plane through the origin<br>rather than true transformations. Also, a theoretical maximum limit of the Lorentz factor is introduced, which<br>leads to an extension of Lorentz transformations to luminal inertial reference frames and raises a conceptual<br>question about the status and role of the symbolic quantity ‘c’, commonly called the speed of light in vacuum,<br>as the neutrino and particularly the photon have non-zero mass. Therefore, it appears that as long as the nonzero mass of the photon is not taken seriously into full consideration, our current knowledge of physics,<br>astronomy, astrophysics, and cosmology remains not only incomplete but above all vague and doubtful.Moreover, this inclusive note highlights Hassani superluminal spatio-temporal transformations, which possess the algebraic structure of a linear group and serve as a generalization of Lorentz transformations for superluminal inertial reference frames. These transformations are anticipated to be fundamental in superluminal relativistic mechanics.<br><br><br><br><br><br>
