Obviously, rockets *do* work. And yet, there are people who believe they don’t. These people are sometimes flat Earthers, who cannot reconcile space travel with their world view and thus conclude that Its A Conspiracy. Sometimes they are people who fundamentally misunderstand basic physics and believe that rockets need something to push against, thus they can’t work in a vacuum. And then there’s this guy. At least Sir Sic’s mockery of him is entertaining.
As it turns out, I approve of this kind of “other ways of knowing.” I fully support the idea of the US federal Government expending considerable time, funds and efforts to promote this kind of thinking. It’s just that I want them to promote this kind of things *elsewhere.* Convince the Chinese and the Norks and the Iranians to accept this sort of thing and base their space programs around it.
