Some call them doomsday ships. These lightspeed ships have no destination at all. They turn their curvature engines to maximum and accelerate like crazy, infinitely approaching the speed of light. Their goal is to leap across time using relativity until they reach the heat death of the universe. By their calculations, ten years within their frame of reference would equal fifty billion years in ours. As a matter of fact, you don’t even need to plan for it. If some malfunction occurs after a ship has accelerated to lightspeed, preventing the ship from decelerating, then you’d also reach the end of the universe within your lifetime.
By many accounts, this is one of the best science fiction books ever written. The volume is the third in the Three-Body Problem trilogy and the best of all three. The story follows the development of humanity after the encounter with the aliens and finding the precarious balance. Many eras pass by, each one bringing amazing concepts and developments, surprising the reader. The protagonist is this time Cheng Xin, an aerospace engineer, who is not a driver, but an anchor for the narrative. She is placed in the middle of all important decisions, from Swordhandler to speedlight ships development. However, her decisions are only a consequence of being chosen as such by humanity.
Trisolarians become at the end allies in an ending universe, gargantuan, dark and soulless. The Dark Forest remains a grim fact of the universe for the author, following the same rule less world perception developed by Thomas Hobbes: Homo homini lupus, but on a cosmos scale.
The boundless imagination of presenting new eras, technologies and aliens is mindblowing. The author manages to give the right length of description with unprecedented precision: enough to give the essence of an era, summarizing the relevant developments.
The logical tightness of the tale is astonishing, managing to captivate the imagination of the reader and make him wonder of what could it be beyond the stars. The concepts brought forward: dark forest, deterrence, civilization development, dimensions of a universe, galactic distances, human choices in face of critical situations, human society evolution having different stimuli, alien courses of action, make the book and the trilogy on par with the best of scifi writers.
These volumes of hard scifi are stunningly well-research as well, replying to practical, physics questions that arise in the wave of civilization and technology development with plausible, well-thought solutions.
No doubt, this is one of the best hard scifi books written so far, bringing enthusiasm for humanity to look at starts and see what lies beyond our planet. This is despite the fact that, ultimately, the story is one of fatalism, where humans, societies and civilizations, are at the mercy of cosmic events.
