Falling into Blue

In ancient times, there was a question. If a plane crashed and you survived and were saved by someone wearing an animal skirt, how would you determine whether you had traveled through time? Answer: Check to see if there are any airplanes flying over the sky above your head. A smarter solution is to observe if there are stars moving quickly. That is the movement of artificial satellites. Lin Yijun has confirmed that there are no spacecraft contrails in this starry sky, there are no weird trajectories of artificial stars, there are no ubiquitous interstellar signal towers, and even the energy form is wrong. Lin Bingjun buried his head in tears, Guanghui didn't understand why, and gently held the commander in his arms, while Dafeng beside him saw his eyes burning. .
