General relativity tells us that strong gravity can distort space, and theoretically there is a possibility of space folding. In the cabin of the Air Force's measurement and control troops, the author found that the "space" here seems to be folded and reconstructed during the day night transition. Transforming finite space is their working philosophy here. Entering the cabin, the first thing that catches the eye are two tables. The officers and soldiers told me that the busiest thing here is them - during the day, they can be dining tables, study tables, conference tables; At night, lowering the tabletop and merging it with the chairs on both sides, it became two beds again. Feeling cramped, the deep roar of the oil engine echoed in the narrow space, and the air was filled with the smell of sweat mixed with engine oil. The sense of confinement in the physical space followed closely. In the interview, we calculated a set of data: 6 people, 14 square meters. Excluding the storage area for materials, it belongs to each officer and soldier and is less than 2 square meters. However, in their mouths, the understanding of space is "infinite" - "wherever our footsteps have been, it is our space." The scorching sun of the Gobi once tanned their skin, and the sandstorms caressed their faces over and over again; The humid monsoon of the island has soaked their training uniforms time and time again, condensing layers of white salt frost... The thousands of miles of rivers and mountains that these wheels have rolled over and stepped on are the expansion of their space and the extension of their battlefield. Wherever the task is, the sky and earth are their space. At this moment, the narrow space inside the shelter carries the boundless mission territory in their hearts. When their living space is compressed, their career map extends between mountains, rivers, and streams; When the dimension of reality is limited within the cabin, their spiritual coordinates have already spread throughout the world. The more grand our career is, the more vast our space will be. ”This is the unique and magnificent "space view" of the Air Force's measurement and control troops in the new era. They weave invisible latitude and longitude with measurement and control equipment, depicting the outline of the motherland with a torrent of data, filling every inch of space with a loyal background, and making every coordinate shine with the light of progress.
