It has been 40 years since the fabled Apollo moon landings. For as many years, there's also been a controversy between those who accept the landings as legitimate, and those who believe they were faked. I propose a third position: Humans did go to the moon, but what we saw on TV was completely faked – by none other than the great filmmaker Stanley Kubrick.
The writers of Star Trek would have us believe that humans can somehow endure every kind of radiation to successfully colonize other planets. But it will probably never happen. Rather, the true frontier is the mystery of time.
