This paper analyzes the experiment presented in 2019 by the Event Horizon Telescope (EHT) Collaboration that unveiled the first image of the supermassive black hole at the center of galaxy M87. The intended aim of the paper is to assess whether the EHT Collaboration has made an “inference to the best explanation” (IBE) to conclude that the data effectively confirm the hypothesis that the object at the center of M87 is in fact a supermassive Kerr rotating black hole. I demonstrate that the EHT Collaboration has applied an IBE. It is shown that the hypothesis that at the center of M87 there is a supermassive Kerr rotating black hole was already the best explanation at the time in which the 2017 EHT experiment was conducted. My analysis is intertwined with considerations on realist and empiricist interpretations of IBE, which are used to assess whether the conclusion that the object at the center of M87 is a Kerr rotating black hole implies holding a realist commitment with respect to such object.

EHT黑洞实验是旧实验伪装的新实验吗?

本文分析了事件视界望远镜 (EHT) 合作组织于 2019 年提出的实验,该实验揭示了 M87 星系中心超大质量黑洞的第一张图像。这篇论文的预期目的是评估 EHT 合作组织是否做出了“最佳解释推论”(IBE),以得出结论,数据有效地证实了 M87 中心的物体实际上是超大质量克尔旋转的假设黑洞。我证明 EHT 协作已经应用了 IBE。结果表明,在 2017 年 EHT 实验进行时,M87 中心存在超大质量克尔旋转黑洞的假设已经是最好的解释。我的分析与对 IBE 的现实主义和经验主义解释的考虑交织在一起,
