With the Kuiper Belt being composed of well over 100 million objects - some grand, some insignificant - is it possible to hide an asteroid base from enemy sensors within its confines, combined with the vast distances of space?
- The size for the base would be within an object with a 70 mile circumference. The current population stands at over 350,000.
- Large ships would occasionally be coming and going from his base, smaller mining vessels somewhat more frequently.
- The enemy searching for them has a deep-seated fear and loathing for true AI. They certainly have advanced computer systems, but nothing independent like an AI powered probe would ever be used.
- The colony/base was established 70 years ago. Their enemy has been searching for them nearly as long.
- The "seekers" are a multi-system ruling class. They're widespread both throughout the galaxy and our system, and have superior technology to the "hiders" - the seekers outpace the others by around 600 years. However, the hiders have certainly managed to glean a lot of their enemy's techniques and tech over the decades. The hiders do have fully-sentient (benevolent) AI systems to assist them in their quest for survival.
