Why has the completion of the main body of China's FAST (500 meter aperture spherical radio telescope) attracted warm attention at home and abroad? There are three reasons. First, it can see far. As the radio telescope with the largest caliber at present, FAST can theoretically receive electromagnetic signals beyond 13.7 billion light-years. Second, it is very flexible. FAST's cable net structure can change with the movement of celestial bodies, greatly improving the observation efficiency. Third, it is high precision. FAST's structure has millimeter accuracy requirements everywhere: it is used to weave steel cables as thick as the arm of the cable net, the machining accuracy is controlled within 1mm. The final accuracy of the antenna is 3mm and the manufacturing accuracy of the small panel is 1.5mm. All this means that we will be able to listen to the voices from deeper in the universe and observe the more hidden mysteries of the universe.
The most suitable title for the above text is 'China's FAST has three advantages'.
