Beyond the Speed of Light

According to one defense of the thesis that the Speed of Light is the maximum Velocity, if something could exceed it, the object might go either backwards or forwards in Time.  Now, why that would be a problem is unclear, but, regardless, the defense presupposes the same premise that the thesis uncritically does.  For, as has been previously discussed, Light is both an object of observation and a condition of it.  So, in the case of the latter, applying the Kantian critique, if something exceeds the Speed of Light, it is simply unobservable.  In other words, the thesis, and its defense, presuppose that Light is only an object of Description, and not a factor in Interpretation.
