First off, I'm curious about the accuracy of this paper:
http://www.orionsarm.com/whitepapers/TraversableLorenzianWormholes-Overview.pdf
I don't know nearly enough about GR to understand the math of the paper. It seems legit to a layman like me, but it IS posted on a hard sci-fi website, not any academic institution. To summarize, the paper claims that the exotic matter requirement for a traversable wormhole of arbitrary size can be placed easily within the realm of quantum effects (like the Cassimer effect). This has something to do with changing the limit from asymptotically flat to increasingly flat. I know what asymptotically flat means, but not increasingly flat, or weather or not that is feasible.
Second, I'm wondering about what traversable wormholes would actually look like. I've seen simulations of the visual effects created by black holes, but I'm not sure traversable wormholes would look in any way similar. For one, I wouldn't expect any redshift, because I assume that would also imply time dilation and probably extreme tidal forces. Also, I would of course expect to see light from the other side of the wormhole, which obviously is not considered in any visual simulations of black holes.
And third (yes, I'm really going that far) I have a question about the actual formation of a traversable wormhole. What basically is the process for creating one? I know there are various models, so there may not be a universal explanation. I know the original proposal was an exotic matter shell surrounding a concentration of mass, although this wouldn't allow passage. In any case, my most pertinent question about this is where the other end of the wormhole would end up? Would it start at the same point, and separate? Or would it open up in some random region of space? Or (probably most likely) do we just have absolutely no idea?
Okay, that was a lot of questions so I don't blame anybody for not answering all of them. Any little bit would be helpful. Thanks.
