Based on the strong penetrability, cross-time and space propagation, and low interaction characteristics of neutrinos ("ghost particles"), the science fiction logic of "neutrinos can carry cosmic-level information and penetrate space-time barriers" is constructed. Through a new generation of neutrino detectors, humans have captured a signal from the "Vega Galaxy Civilization" 2,000 light-years away. The content of the signal is actually an early warning about the "collapse of space-time in the Milky Way," and the future trajectory of human civilization is hidden in the early warning.
