Well, I respectfully differ (again!
)
First, I believe it's not teleportation. I think teleportation involves converting the human body (or the thing you want to move) into information, moving the information to other site and then, reconstructing the body or thing from that information.
Second,
wormholes have a large problem: the tidal forces. Those forces arise from the fact that when a body attracts another, the distance between the different parts of those bodies are not the same. Portions of the sea are closer to the moon than others, so they experience a larger force and thus, move or "bulge".
An astronaut falling in a wormhole would experiences several funny things, similar to the ones he'd experience when reaching the speed of light (time will dilate, distances would shorten when seen from outside the wormhole). Nothing impassable, as I read.
If he is falling the enormous gravitation wouldn't crush him: he is falling, so he doesn't weigh more, the same way a rock falling doesn't "crush" under his own weight, because it's not supported by anything.
However, our hipothetical astronaut has a great problem in a wormhole:
the difference in the force of attraction that his feet feels (if he is falling "feet down")
and the force that his head experiences becomes larger and larger the closer he gets to the singularity (the black hole that creates the wormhole).
Finally, not even close to the event horizon (the "edge" of the black hole), he will be torn apart.
The travel I "described" can be realized with "simple" extrapolations of devices already invented: this kind of travel requires "incremental" technology. If we do not want to use antimatter (it sounds a little "out of this world") you can annihilate matter and obtain energy using a "common" nuclear fision or fusion reaction, so I believe is doable.
It is a problem of engineering. All we need is time, money and ingenuity.
A travel through a wormhole requires a "bending" of the physical principles we know. So, I don't think they are usable for trips, unless a great advance happens in science.
It is a problem for inventors, a harder proposition to accomplish.
As for the space technology coming from Russians or Americans, well, I think
everybody knows the technology was developed in Germany in 1920-1930. America and Russia (and Ukraine!
) took the technicians and scientists after World War II and gave them the money and the "local personal" they needed.
Old and rusty V2 engine found at the Dora tunnels in 1990, when the tunnel was reopened
Saturn F1 engine: direct descendant from V2 engine down to the cooling and preheating "cyclone"
That would be teletransportation...
