Singularity is a KSP mod aimed at adding black hole shaders, including gravitational lensing and accretion disk. for use with planet packs and custom systems. The mod does nothing by itself and needs to be configured.
Other possible uses include wormholes, stars with gravitational lensing, “white holes” ( a sort of black hole with negative gravity, pushing away light).
