Hello there. This is my first post here but just spent the last couple of hours browsing the forums. There seems to be some pretty smart people here and so I would like enlist their help in helping me understand some of the principles of time and space.

A little background; My name is Nick Dismas, I am 24 and live in Manchester, England. I am working to become a freelance writer and illustrator and at the moment I have an idea for a story that I am interested in pursuing. At the moment though that's all it is; an idea.

In a nutshell you might say it's a time travel story, and so it is this the main area I'm looking for information. I've spent the past few weeks reading various texts but to my right-handed brain this has raised more questions than it's answered. I get the feeling that by mentioning that I want to develop a time travel story that there will be a collective groan across the forum, but I hope you'll understand that the time travel is merely a vehicle for a more character driven plot-line. However, I want to make sure that this story if based as much on science-fact (or at least credible science-theory) as possible.

I feel like I'm rambling. Sorry.

So, to start with; I think I've settled on wormholes as the method for the (backwards) time travel. Our highly advanced far-future selves developing the ability to fabricate and sustain an Einstein-Rosen bridge (that right?) and move through it to other points in space and time.

First question; how would you expect to be able to determine a given point in space and time and how accurate would you expect this determination to be?

Okay, that was two questions, but you get the idea.

Okay... go!

I don't think that theory is likely to determine when and where the end point of a wormhole would come out and it would be necessary to actually build some and study the characteristics empirically. The time is probably the same for co-moving observers at each end of the wormhole (that is "now" here is the same as "now" there) but you'd need a synchronization mechanism to be sure and I'm not positive I'm right about that.

The "where" is likely to be the problem.
 
OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...
In this video I can see a person walking around lines of curvature on a sphere with an arrow strapped to his waist. His task is to keep the arrow pointed in the same direction How does he do this ? Does he use a reference point like the stars? (that only move very slowly) If that is how he keeps the arrow pointing in the same direction, is that equivalent to saying that he orients the arrow wrt the 3d space that the sphere is embedded in? So ,although one refers to intrinsic curvature...
ASSUMPTIONS 1. Two identical clocks A and B in the same inertial frame are stationary relative to each other a fixed distance L apart. Time passes at the same rate for both. 2. Both clocks are able to send/receive light signals and to write/read the send/receive times into signals. 3. The speed of light is anisotropic. METHOD 1. At time t[A1] and time t[B1], clock A sends a light signal to clock B. The clock B time is unknown to A. 2. Clock B receives the signal from A at time t[B2] and...
