This is one of the 13 short stories from my Echoes of the Mind's Eye collection that has also appeared in other collections since 2011.
This short story poses a novel theory as to the role of black holes in both the creation and destruction of an endless number of universes that coexist in an incomprehensibly complex multiverse. It is a cautionary tale about the arrogance of scientists who are the cosmic equivalent of amoebas attempting to discern the secrets of the universe by thoroughly examining within the limits of their perception the drop of pond scum they inhabit. It is also a cautionary tale about the ability of determined, well-funded terrorists to begin the process that will lead to the destruction of our corner of the multiverse by the creative use of materials at their disposal.
The end is very, very near and there is absolutely nothing we can do about it.
