Does the vast and empty universe have metaethical upshots, perhaps supporting metaethical nihilism or at least counting against robust moral realism? Philosophers have not been kind to this cliché, and most think that Thomas Nagel and Guy Kahane refuted it. I argue, using Inference to Best Explanation, that the huge empty skies should indeed make us less confident that anything robustly matters.
