在刘慈欣的科幻巨著《三体·死神永生》中，“阶梯计划”是地球人类为了与外星文明“三体”进行交流而实施的一项重要计划。该计划的核心内容是发送人类样本到太空，以供三体人研究。然而，计划中并没有选择发送人类的受精卵，而是决定发送人类的大脑。这一决策引发了广泛的讨论和猜测。
根据已有的知识和事实，我们可以从几个角度来分析这一决策的合理性：
首先，大脑是人类智能和意识的载体，而受精卵则是一个未发育完全的生命体。发送大脑可以更直接地向三体人展示人类的智慧和文明，从而提高交流的效率和深度。
其次，大脑的体积和重量远小于一个受精卵，这意味着在太空运输和发送过程中，大脑将更为经济和高效。此外，大脑的保存和发送技术也相对成熟，可以确保信息的完整性和安全性。
再者，发送大脑还可以作为一种象征，代表着人类文明的勇气和决心。通过这种方式，人类向三体人传达了一种开放和合作的信号，有助于建立双方的信任和理解。
最后，从科幻作品本身的情节推敲，发送大脑可能还有更深层次的象征意义，即人类希望通过这种方式传递人类的情感和思想，让三体人感受到人类的生命和价值。
综上所述，《三体·死神永生》中“阶梯计划”选择发送人类大脑而非受精卵，是基于对人类文明象征意义的考虑，以及对太空运输技术的实际考量。这一决策不仅符合故事情节的需要，也体现了作者对人类文明本质的深刻思考。

Title: “Why the ‘Staircase Plan’ in ‘The Three-Body Problem: Death’s End’ Chose Human Brains Over Sperm?”
Keywords: Staircase Plan, Human Brain, Expedition to the Universe
News Content:
In Liu Cixin’s science fiction epic “The Three-Body Problem: Death’s End,” the “Staircase Plan” is an important initiative implemented by Earth humans to communicate with the extraterrestrial civilization known as the “Three Body.” The core of this plan involves sending human specimens into space for study by the Three Body. However, the plan did not opt to send human sperm but instead decided to send human brains. This decision has sparked widespread discussion and speculation.
Based on existing knowledge and facts, we can analyze the rationality of this decision from several perspectives:
Firstly, the brain is the carrier of human intelligence and consciousness, while sperm is an undeveloped life form. Sending the brain can more directly demonstrate human wisdom and civilization to the Three Body, thereby enhancing the efficiency and depth of communication.
Secondly, the volume and weight of a brain are far less than that of sperm, which means in space transportation and sending, the brain will be more economical and efficient. Additionally, the preservation and sending technology of the brain is relatively mature, ensuring the integrity and security of information.
Furthermore, sending the brain can also serve as a symbol, representing the bravery and determination of human civilization. In this way, humans send a signal of openness and cooperation to the Three Body, facilitating the establishment of mutual trust and understanding between the two sides.
Lastly, from the perspective of the plot of the science fiction work itself, sending the brain may also have deeper symbolic meanings, namely, humans wish to convey their emotions and thoughts through this method, allowing the Three Body to feel the value of human life.
In summary, the decision to send human brains rather than sperm in the “Staircase Plan” of “The Three-Body Problem: Death’s End” is based on considerations of the symbolic significance of human civilization and practical considerations of space transportation technology. This decision not only meets the needs of the story plot but also reflects the author’s profound thoughts on the essence of human civilization.
