Jason Lisle has formulated a model that purports to solve the light travel time problem (LTTP). The model is based on the Reichenbach ε formalism of specifying remote simultaneity by a coordinate convention (Reichenbach 1958, 127). The convention is directly based on the assumption that the one-way speed of light cannot be measured, since remote clocks cannot be synchronized. This conventionalist approach apparently allows one to alter the one-way speed of light such that incoming light to an observer can be made arbitrarily large by a suitable choice of the ε parameter. We show herein that such is not the case. The ASC model explicitly assumes the mathematical structure of Minkowski space and the foundations of special relativity (SR). Minkowski space presupposes an isotropic physical speed of light. The assumption of Minkowski space, as correctly embraced by Lisle, is incompatible with the conclusions of ASC which purports that the incoming speed of light can be made arbitrarily large.
