Some important and decisive observations allowed a widespread and almost unquestionable acceptance of the big bang cosmology, but we can admit and search other factors that have contributed and continue to contribute to the enormous acceptance and great popularity of this cosmological conception, not only inside but also outside of cosmology and even in numerous no scientific contexts. To find some of those factors, a case study was undertaken based on thematic analysis , an analytical tool which is based on the idea that the scientific activity, in addition to a theoretical and an experimental dimensions, has a third dimension with psychological and cultural elements called themata that strongly influence the construction of scientific theories and also their acceptance or rejection. This case study focused on the most important founding texts of big bang cosmology, namely articles and books of Alexandre Friedmann, Georges Lemaître, and George Gamow, covering three decades of important developments (1922–1952), and the founding texts of its great rival, the steady-state cosmology. This article presents a summary of the main results of this case study, which allowed to identify several themata with a very important role in the big bang cosmology: differentiation and unification (methodological themata ); unity, creation, change, evolution, constancy (of mass/energy), simplicity, life cycle, circularity, and disorder (conceptual themata ). All these themata form a methodological and conceptual matrix—with a triple dimension: historical, transversal/cultural, and psychological—that can help explain the acceptance and popularity of the big bang cosmology within and beyond its disciplinary boundaries.

为什么大爆炸如此被接受和流行：主题分析的一些贡献

一些重要和决定性的观察使大爆炸宇宙学得到广泛且几乎无可置疑的接受，但我们可以承认并寻找其他因素，这些因素已经并继续促成这一宇宙学概念的广泛接受和广泛流行，不仅在内部，而且在在宇宙学之外，甚至在许多没有科学的背景下。为了找到其中的一些因素，基于主题分析进行了案例研究，这是一种分析工具，该分析工具基于科学活动除了理论和实验维度之外还具有心理和文化元素的第三维度强烈影响科学理论的构建及其接受或拒绝的主题。本案例研究侧重于大爆炸宇宙学最重要的创始文本，即 Alexandre Friedmann、Georges Lemaître 和 George Gamow 的文章和书籍，涵盖三个十年的重要发展（1922-1952），以及其主要竞争对手的创始文本，稳态宇宙学。本文概述了本案例研究的主要结果，它允许识别在大爆炸宇宙学中具有非常重要作用的几个主题：分化和统一（方法论主题）；统一、创造、变化、进化、恒常性（质量/能量）、简单性、生命周期、循环性和无序（概念主题）。所有这些主题形成了一个方法论和概念矩阵——具有三个维度：历史、横向/文化、
