If a geometrically designed physical system was such that a) the collapse(or extended expression of the system) caused "stacked" acceleration to potentialize the speed of light towards the end, and b) that the input force and structural strength of the system was high enough, what would happen? This has bugged me for some time. Now, my developed thoughts are this: the system MUST FAIL. That is, the system must fail to achieve speeds in excess of or even nearly approaching the speed of light. Fine, I understand that. But how is this failure characterized with stable potentialization of C through a specially designed mechanism? I would propose that a "lock" would occur, specifically a "C-lock" if you will, that would forbid the complete expression of the system, wholly unrelated to friction or the "next-stage" force reduction common in stacked accelerative arrangements. Any thoughts on this?
