The 2011 Nobel Prize in Physics was awarded to researchers from the Supernova Cosmology Project and the High- z Supernova Search Team for the discovery of the accelerating expansion of the universe. In this paper, I provide a historical analysis of the supernova cosmology evidence put forward by these teams for the accelerating universe, in terms of an iterative model of scientific progress developed by Hasok Chang in the context of his study of the development of measurement standards. I argue, using the key concept of epistemic iteration, that the iterative model adequately accounts for evidence production in experimental science as well. In order to apply Chang’s model to the experimental evidence for the accelerating universe, I introduce the concept of endorsement as a particular mode of progress, and argue that supernova scientists produced an endorsed measurement system to claim evidence for their discovery. Furthermore, I show that the credibility of the evidence was not based on a particular measurement, rather, what proved to be decisive was the “robust consistency” of many individual results.

加速宇宙的证据：认可和强大的一致性

2011年诺贝尔物理学奖授予了超新星宇宙学计划和Highz超新星搜索团队的研究人员，以表彰宇宙加速膨胀的发现。在本文中，我将根据Hasok Chang在他对测量标准发展的研究中开发的科学进步的迭代模型，对这些团队为加速宇宙提出的超新星宇宙学证据进行历史分析。我认为，使用认知迭代的关键概念，迭代模型也足以说明实验科学中的证据产生。为了将Chang的模型应用于加速宇宙的实验证据，我介绍了认可这一特定进步方式的概念，并认为超新星科学家生产了一种认可的测量系统，以为其发现提供证据。此外，我表明证据的可信度不是基于特定的度量，而是被证明是决定性的是许多单独结果的“稳健一致性”。
