Is a warp drive actually possible to create? If so, how long until we can develop one? Is it at all possible that they could be developed during our lifetimes? I'm asking because of this article http://www.redorbit.com/news/space/...ot-accidentally-invent-the-warp-drive-050115/ which also leads me to ask, what are the differences between a warp drive and an EmDrive? Is it at all possible for an EmDrive to be developed? Could the development of an EmDrive really lead to the development of a war drive? Do either the emdrive or the warp drive "break the laws of physics"?
