I started a thread in time machines and experience, that included two photographs. About the time experiment thats about to be conducted at the university I work this coming Friday. Went into great detail about it and one of the photographs had a picture of the superconductor and its name. Come back to the forum and the threads disappeared. Now I briefly saw something on this forum from Num7 saying they had been a problem with the hosting company and a number of post has disappeared, a reasonable explanation. But this evening I got a phone call from a colleague saying that tomorrow there are two men from the Ministry of Defence whom wish to speak to me. ODD.
