In 2342, the “Milky Way All-Sky Observation Array,” spanning the entire ecliptic plane of the solar system and composed of hundreds of millions of distributed miniature probes, detected crucial data: the helium-burning rate in the core of “Flameheart,” a massive star 42 light-years from the solar system, had surged abnormally. Spectral analysis confirmed that it would explode as a Type II supernova in 750,000 years. Simulations showed that the resulting gamma-ray burst would penetrate the solar system's magnetic field within 100,000 years, while an interstellar shock wave would strip away Earth's atmosphere over the following 500,000 years, utterly destroying the biosphere.
Humanity's only chance of survival was the “Starship Project,” led by the “Interstellar Survival Alliance,” a supranational organization combining global technology and resources. Its goal was to build the first Caplan thruster. The technology was based entirely on Matthew Caplan's theoretical framework, consisted of three inseparable subsystems, and required breakthroughs across numerous limits of physics and engineering.
Of course, this book has bugs too.
The author takes the future solar system as the background and tells the story of scientists' various efforts to solve the problem of human beings leaving the solar system and their struggles with various difficulties and hardships. Worth reading!
