3D Memo Three Body Countdown

Countdown refers to the mysterious phenomenon observed by the protagonist Wang Miao, where he sees a constantly decreasing number in his field of vision and in photographs. This countdown is actually caused by the Trisolaran civilization using "sophons" to interfere with Earth's scientists, aiming to demoralize them and halt technological progress. The countdown symbolizes the imminent threat posed by the Trisolarans and the urgent crisis faced by humanity.
