I don't see how the third theory of what happens to the spaceship - i.e. it reappears at a remote galaxy - is compatible with Conservation of Mass. Even if the spaceship reappears in its new location immediately, to a stationary observer, the two events (disappearance into black hole and reemergence elsewhere) are not simultaneous to a moving observer according to Special Relativity, so Conservation of Mass has been compromised.
