It's a combination of Gravitanium, Invincium and Arcrion. (Arcrion is the Telurian Field emitter.)
Erinaum holds the patent do not steal.
We were able to utilise the technology that we use to close singularities to shrink the singularity so that it does not pose any threat.
You cannot shrink an object of infinitesimally small volume. Even if you were, it would make it worse, since it would make the object more dense. The black hole would have to be pulled apart, something that only a super powerful Deconcentrator could do. That power, I do not have. When it would be pulled apart, the result would be the mass that was put into it taking up its original volume. Some of the mass could be converted into Gravitanium, though since Gravitanium comes from high mass objects, especially wormholes.
