Abstract

This chapter considers simpler prototype of a Star Trek transporter: a matter‐energy‐matter (MEM) converter. The MEM converter works in three stages. First, it scans an object and records the positions and states of all of the fundamental physical particles that compose it. Second, the converter disintegrates the object. Third, it assembles an exact replica of the object by repositioning fundamental physical particles according to the record it created during its original scan. Constitutionalism is an exciting theory that is the basis for many Star Trek episodes. But it faces the fission problem, which Commander Riker experiences first hand in second chances (TNG). If survival is just as good as identity, then even if the human who comes out of the transporter isn't really the human who went in, the replica is still indistinguishable from that human.
