Distant Telemetry Guidance

Faster-than-light travel is inherently dangerous. Various technologies exist to achieve supra-liminal speeds, but they all carry risks: colliding with a gravity-well, emerging within a star, or being torn in half by a closing portal. Distant telemetry guidance, or DTG, gives a ship a fighting chance of actually navigating deep space.
The technology has been discovered, lost, and rediscovered time and again, the basics remaining the same each time:
Black holes, contrary to what once believed, actually emit a type of exotic matter called 'rejectonite.' This bizarre substance defies the laws of gravity, and has a strange polar opposite reaction to the specific black hole that spawned it. Using it as a sort of reverse magnetic compass, a DTG navigation computer can tune in to the exact position of that specific black hole (typically the large one at Galactic Center), and determine their exact point in space. Complex AI and charts allow a ship to then make FTL jumps with far less worry about running into something else.
Simply put: without distant telemetry guidance, galactic travel would be largely impossible.
