From the end of TFA: Indeed, it’s so incredible that some might see in this accomplishment hints that there could be more at work than nature here. Even before these measurements were taken by NICER, a group of researchers at the Free University of Brussels led by Clément Vidal explored whether these x-ray millisecond pulsars could have been arrayed around the galaxy on purpose. In a preprint titled “Pulsar Positioning System: A quest for evidence of extraterrestrial engineering,” they examine that albeit remote possibility.
