The warp drive concept is a fascinating idea as a means to get from point A to point B in a much shorter time as opposed to traveling through normal space, which would undoubtedly take many years to centuries. Still, there is something fishy about warp drive. While many difficult issues have been addressed, such as the negative energy requirement, some rather simplistic problems have been ignored (or rather left to be assumed by the reader). Such as obtaining the mass necessary to curve spacetime in order to induce the warp drive. From the stand point of General Relativity, this is not an initial concern, however it is for body which obeys conservation laws. An object of several tons can not generate a mass several times its own magnitude through any known scientific process. And even if it were possible, one runs into the very severe risk of generating a singularity in spacetime, i.e. a black hole. Again, even under the best of circumstances, it appears that negative energy densities are required for the warp drive Thereby from a physical point of view this makes the warp drive look even more unrealistic. A more plausible means of intestellar travel are the jump gates depicted in Bablyon 5. In the fascinating book entitled, "Indistinguishable From Magic" by the late Robert L. Forward, renown physicist and science fiction writer, he discusses the possibility of time machines, reactionless drives, faster than light drives and building real starships. In one section of the book, Mr. Forward talks about two methods of traveling faster than light. Here are the two possibilities: 1) Find some future technology that allows movement through space between "here" and "there" faster than light. 2) The other way is to obey the cosmic speed law limit, but find some method of getting from "here" to "there" without having to go through all that empty space in between. In other words, the space warp. Unfortunately, the author does not give any details on how method number one could work in theory. However, for method number two, he states that space warps are “bridges” or “tunnels” that shortcut through higher dimensions from one point in space to another. This particular space warp concept that is an exact solution to the equations of the Einstein Theory of Gravity, and yet does not involve singularities, or even stellar masses. This is known as the Morris-Thorne Field-Supported Space Tunnel. These are tunnels through space that are kept from collapsing to a singularity by threading the throat of the tunnel with special fields. The fields holding up the Space Tunnel have to be exotic fields that have a tension greater than their energy density. Such fields are known to exist in high energy density matter such as is found in neutron stars. Other versions of these fields have been made in the laboratory at low energy densities. These exotic fields holds the Morris-Thorne Space Tunnel open, thereby allowing a starship to pass through. Thought anyone?
