No, SR is just a statement about the fundamental laws of physics being Lorentz-symmetric. This is still true even if you choose not to use the Lorentz transformation to define your set of inertial coordinate systems. (Also, the choice of what coordinate system to use is not in itself an 'interpretation of the laws of physics', any more than your choice of where to place the origin of your spatial coordinate axes is an interpretation of the laws of physics--it seems to me that the only way the LET can count as a distinct 'interpretation' is if it postulates some unobservable physical entities which are governed by non-Lorentz-symmetric laws.)Aether said:Suffice it to say that SR is a coordinate-system dependent interpretation of the laws of physics, and as such it should not be confused with "reality" per se.
