Tianxiaism in an experimental interstellar scenario: Negotiating with the trisolarans through quantum entanglement

Research on interstellar relations offers forward-looking theoretical and practical significance. This paper expands the scope of international relations into the interstellar domain, using a comparative analysis of realism versus Tianxiaism to present a pluralistic cosmological perspective with logically derived hypothetical scenarios of inter-civilizational interaction. In doing so, a Tianxiaism theoretical paradigm is introduced and metaphorically applied via quantum entanglement as a mode of communication and negotiation with the Trisolaran extraterrestrials in the experimental interstellar scenarios. The Tianxia paradigm helps to tease out the logical structure and points of contention in interstellar relations, offering a preliminary framework for Interstellar Relations Theory. By mirroring contemporary international relations dynamics, we show that the realist “law of the jungle” at the cosmic level (embodied in the “Dark Forest” scenario) drives civilizations toward mutual destruction and cosmic ruin. In contrast, the Tianxiaist emphasis on peaceful coexistence suggests the possibility of interstellar symbiosis in a hypothetical scenario.
