LOL yeah. I finished a series last year for Discovery channel about Stephen Hawking (which is due out next month) and he talks of the use of anti matter to drive starships to lightspeeds and beyond time travel. Its actually a possible theory. Though for this type of thing I dont worry too much with the technicalities of such theories, it is what it is and does what I want it to do LOL good stuff. better late than never cheers bullet Jay
