 Yes, and I don't know. NASA has in their astrobiology roadmaps, every time they publish, a section about technosignatures now. And so I know they're looking for them. And people do papers on them, of course. But there's nothing really as definitive as my website or my book where I just put it in everybody's face and say, explain this, because you can't. So, yeah, NASA's looking at it. Does NASA know what I'm doing? I don't think so.
