For sure you have seen the classic movie 'The Time Machine', where the Victorian epoch time traveller went to a future far, far away into the world of the future where the old struggle of good against evil will. Then, you also might have heard about the story, where aliens from Mars started war against earth, but finally are going to die because of earth's microbes. Or maybe also the story, when famous actor and director Orson Wells in 1938 produced a radio show from this story, which was mistaken by a lot of American people to be a true radio report about an alien invasion of the USA, causing a real life panic?
