“The worm hole drive itself requires something else, beyond contemporary physics.”
Yeah, that’s a pretty big issue. It might make a feasible mode of travel, but before we can see if it’s feasible, we have to figure out if it is even possible.
Personally, I doubt we will ever be able to travel through a wormhole, either a natural one, or one we generate, and survive the trip. I believe we’d have to endure some pretty immense forces, akin to what you’d experience inside a black hole, and what could protect us from that?
Perhaps a combination of the warp and wormhole concepts could work. If you could create a space-time warp bubble around the ship, that is about the only thing I can think of that might protect you while you traverse the wormhole.
The worm hole is not gravitationally-induced it is electrically-induced.
A worm hole drive is a ‘warp drive’. ‘Holes’ of larger distances correlate to increased relative velocity. It is not a “hole” per se as it is a modification of the space the vehicle occupies to another point in space. The change in location occurs at the speed of light (electricity). The distances between the jumps can represent (in aggregate) a velocity much greater than the speed of light all the while vehicle occupants experience zero inertial effect.
