摘要
量子引力所提出的主要问题之一是时空在物理学中到底应该以一种什么样的地位出现。超弦和圈量子理论的不同时空预设及其复杂的形式体系为人们理解它们的物理和哲学含义给出了方法论的启示。量子引力时空理论的纵向语境分析,表明了数学成果的现存性及对它的分析决定了时空理论形式语言的形式语境、语义语境及语用语境的变换；量子引力时空理论的横断语境分析,显示了量子引力理论提出的现实语境和对其进行求解的语境选择所具有的重要意义。正是在量子引力理论所具有的语境预设的基础上,使人们看到了从本体论、认识论和方法论上对时空理论把握的宏观与微观、单一与多样性统一的哲学意义。
One of the primary questions of quantum gravity is the position of space-time in physics. Thus the different space-time presuppositions in superstring theory and loop quantum theory, and their complicated formal systems,provide methodological indications for understanding physical and philosophical meanings of quantum gravity.As the longitudinal contextual analysis shows,the existence of mathematical findings and their analysis determine the changes in syntactic context,semantic context and pragmatic context of space-time formal language.A diatropic contextual analysis indicates the actual contexts in which quantum gravity theory is proposed and the importance of explanatory contextual choices.In conclusion,it is on the basis of the presuppositions of quantum gravity that we realize the philosophical meaning of grasping the unification that develops from macrocosm to microcosm and from singularity to variety in the light of ontology,epistemology and methodology.
