Heard It in the Morning

The quote "Hear the Way in the morning, die content in the evening!"（朝聞道，夕死可矣) is from Chapter Li Ren, Analects of Confucius. It expresses an irresistible curiosity and a passion for wisdom.

Ding Yi drives around the entire Earth in a new particle accelerator with his wife and daughter. Although they don't see anything outside, Ding Yi insists as a theoretical physicist that the human imagination offers the best experience. Shortly before the first experiment, the entire particle accelerator vanishes. An alien projected as a levitating human appears, calling itself a dehazardification officer and reveals to have removed the particle accelerator so that humanity won't cause a vacuum decay. Ding Yi asks how they can find out about the Grand Unified Theory otherwise, but the dehazardification officer claims that it's impossible without initiating vacuum decay and destroying themselves. Although it knows the Grand Unified Theory, whose essential data was transmitted by an ancient alien civilization one tenthousandth of a second before their annihilation in his former home universe, a prime directive forbids sharing it with humanity. Ding Yi asks if telling and then destroying him is possible, to which the dehazardification officer agrees. Hundreds of scientists then gather to learn the ultimate truth about their subject in exchange for their life. Ding Yi is asked by his daughter to step down, but declines and dies knowing the Grand Unified Theory in front of her. His wife let their daughter watch, so she never becomes a physicist, but fifteen years later she still does. In a conversation about the past, her mother learns about the radical different philosophy her daughter adopted, valuing the implications of physics for humans unlike her father.
