Abstract

We examine the justification for taking the Event Horizon Telescope’s famous 2019 image to be a reliable representation of the region surrounding a black hole. We argue that it takes the form of a robustness argument, with the resulting image being robust across variation in a range of data-analysis pipelines. We clarify the sense of “robustness” operating here and show how it can account for the reliability of astrophysical inferences, even in cases—like the EHT—where these inferences are based on experiments that are (for all practical purposes) unique. This has consequences far beyond the 2019 image.
