Antimatter torp Question

[Dubious]

Magnetic containment fields, quantum effects, hyperbaric laser traps, force fields, take your pick. Energy fields are not "matter", and are currently used to confine plasmas hotter than the melting point of any material on Earth. We have the theory today to postulate how an antimatter drive or torpedo would have to work; it's the engineering which has to catch up. If they can demonstrate the teleportation of information (which they have, it's a quantum effect), and as they have proven the existence of the anti-matter particle, don't worry over anything a "futuristic" game can come up with.
