[QUOTE="spiney, post: 182880, member: 192438"] As was made clear, Bronking, i don't agree with much of what T Napier said, eg ftl travel might be possible. But, you seem to have completely missed the point. Self-contradiction isn't "not allowed" because I say so, but because it's gibberish. That's why perpetual motion (inc. Cavorite, sorry, mentioned it again!) is impossible. Not because "God forbids it", but a because an internal contradiction is set up within the maths, so the outcome just is gibberish. For example - for one observer at a single spacetime "point" - a single external object can't be moving in 2 different directions simultaneously (what does that mean, what would you actually see? If you see 2 things, then that's 2 objects!). The physics/maths no longer "works", because it's become complete drivel. The things you metntioned are NOT counter-examples to this. Yes, everybody 700 years ago though the earth revolved around the sun, for what seemed good reasons! However, the other way round isn't logically impossible! And, the people who believed this were also fully aware that the earth was once thought flat (!), and also knew about Aristarchus: [URL="http://en.wikipedia.org/wiki/Aristarchus_of_Samos"]http://en.wikipedia.org/wiki/Aristarchus_of_Samos[/URL] . Once there were sufficient reasons for believing that the earth went round the sun, then most people did! Radio waves were predicted by Maxwell - of course - using maths/science depending entirely on logical consistency, no self-contradictions allowed! Space travel has been speculated on for hundreds of years, and known to be feasible since Tsiolkovski: [URL="http://en.wikipedia.org/wiki/Tsiolkovsky"]http://en.wikipedia.org/wiki/Tsiolkovsky[/URL] .
