Diaspora (1997)Greg Egan
Chapter 25
In this chapter, Paolo, Elena, and Karpal explore the nature and location of a singularity within an elliptical galaxy, discussing the possibility that the Transmuters intentionally biased its placement. They encounter a mysterious non-sentient entity called a Contingency Handler, which provides unexpected insights into complex astrophysical phenomena, including the fate of a neutron star binary system and the role of extra-dimensional interactions in angular momentum transfer. This revelation partially answers a long-standing mystery that motivated the Diaspora's inter-universal journey.
