A village that housed 65 people had to be moved in order to free up space for the construction of the telescope. Yet that wasn’t even the biggest problem that the Chinese faced while trying to get FAST operative. You see, despite its size, the telescope is an incredibly sensitive piece of equipment, and as a result it needs what’s known as “radio quiet” in order to work properly.
This meant creating an unpopulated area around the telescope, and so more than 9,000 people within a three-mile radius were also relocated. This was, moreover, far from a simple process, and 500 families attempted to take the local authorities to court in order to get compensation. In the end, in fact, the cost of moving local residents was greater than the price of building FAST itself.
