How did the fall of China s FA. ST (500-meter Spherical Radio Telescope) main body cause enthusiasm at home and abroad? There are three reasons. One is to look far. As the largest radio telescope at present, FA. ST can theoretically receive electromagnetic signals beyond 13.7 billion light years. The second is very flexible. The cable network structure of FA. ST can follow The movement of celestial bodies greatly improves observation efficiency. The third is of high accuracy. The structure of FA. ST is full of millimeter-level accuracy requirements: it is used to weave steel wire arm-thick steel cables, and the processing accuracy is controlled to 1 millimeter. Within; the final antenna accuracy is 3 mm, and the manufacturing accuracy of the small panel is 1.5 mm. All this means that we will be able to listen to sounds from deeper in the universe and observe the more hidden mysteries of the universe. What is the best title for this text?

ST has three advantages.", 'Listen to the sounds from deep in the universe together.']
