技术圈作为宇宙晚期物质-能量转化的潜在热力学实体——一个基于耗散结构假说的理论探索

The Technosphere as a Potential Thermodynamic Entity in Late-Universe Matter-Energy Conversion-A Theoretical Exploration Based on the Dissipative Structure Hypothesis

摘要

ΛCDM宇宙学模型所描绘的“热寂”终局未充分考虑与恒星丰度相当的流浪行星的最终命运，构成一个理论上的物质残留困境。本文提出一个探索性框架，将能长期存续的先进技术文明所构建的“技术圈”，概念化为一个宇宙学尺度上的宏观“耗散结构”。基于非平衡态热力学，此类技术圈为维持其低熵结构，可能在宇宙晚期主动地搜寻、获取并转化流浪行星中的重子物质，通过受控核聚变等过程将其转化为辐射能量。这一“主动转化机制”为解决流浪行星残留问题提供了新的物理思路，并暗示技术活动或能成为影响宇宙极长期热力学演化的重要因素。本假说旨在连接天体物理学、热力学与天体生物学，为思考智慧生命在宇宙宏观演化中的潜在物理意义提供思辨基础。

Abstract

The ‘heat death’ finale depicted by the ΛCDM cosmological model fails to adequately account for the ultimate fate of rogue planets, whose abundance rivals that of stars, creating a theoretical conundrum of residual matter. This paper proposes an exploratory framework conceptualising the “technosphere” constructed by advanced technological civilisations capable of long-term survival as a macro-scale ‘dissipative structure’ on a cosmological scale. Based on non-equilibrium thermodynamics, such technospheres may actively seek, acquire, and transform baryonic matter from rogue planets in the cosmic late stage to maintain their low-entropy structure. This conversion, achieved through processes like controlled nuclear fusion, releases radiant energy. This ‘active transformation mechanism’ offers a novel physical approach to resolving the rogue planet residue problem and suggests technological activity could significantly influence the thermodynamic evolution of the universe over extremely long timescales. This hypothesis aims to bridge astrophysics, thermodynamics, and astrobiology, providing a speculative foundation for contemplating the potential physical significance of intelligent life within the macrocosmic evolution of the universe.
