If that is the case, would this even horizion act simular to those around black holes?

I'll get back to you.

The problem with all FTL objects is that their mass as well as their length and their time dilation will become imaginary (that is, a real figure multiplied with i, the square root of -1) according to 1/sqrt(1-v^2/c^2). An imaginary mass, length or time is not defined. This is what the paradox should be about. If, however, we postulate FTL travel is possible, then the imaginary values must make sense somehow, we only don't know so far, let alone know ii and what we are supposed to see of it.

The warp field in Trek solves the problem in that the warp bubble is some kind of separate universe in which exactly the same physical laws apply as outside, and no relativistic effects occur. That means, unless someone looks through a window, it is not possible to determine the ship is traveling at warp.

The border of the warp bubble (be it sharp or not) automatically transforms incoming or outgoing energy or matter to the according state inside or outside the bubble. Let's assume incoming light that moves at c outside, it will still move at c inside the bubble. The question is what the external observer will see. I think it is impossible to look inside the warp bubble, because it moves at v>c and is therefore apparently outside the laws of physics. I doubt that it's possible to see an imaginary dimension of an object that has an imaginary time.

Actually, the effects could be somewhat similar to an event horizon that swallows an astronaut, as observed from outside, whereas the astronaut himself doesn't notice it until he is torn apart.

1) Hawking Radiation. If there is Hawking Radiation emitted from a FOEH, then it must be either very weak or very strong. A miniture Black Hole will be white hot from Hawking Radiation. This would prove harmful for the FTL object if too bright.

2) Entropy. Around Black Holes, the size of the event horizion is porportional to the Black Hole's entropy. If this holds true for an FOEH, then an object returning to slower than light would have some problems with the second law and/or increased Hawking radiation emission (see above).

3) More later. Same Bat time, same Bat Forum.

Well, the dynamics across the event horizion of a FTL object would be quite different. Since light cannot excape, any particle wandering in would be trapped, but the gravitational entering would be virtually nonexistant. To analyze the effects, let me re-iterate an experiment demostrating the basic flaws with modern physics.

Lets say we have two very small, very fine, and very close metal plates. Since there is more space on the outside (rest of the universe) than on the inside (between the plates), there are more virtual particle pair production on the outside. This causes (for reasons that excape me at the moment) a slight inward force on the plates in addition to gravitational attraction. The problem is that, according the the known laws of quantum mechanics, there is both an infinite number of particle-pair productions on either side of the plate system (inside and outside). Most theoritical physicists hope that the two infinities cancle out, but they can't find a way to!!! I think this is really funny, but...

Back to this and it's effects on FTL objects. later, though.

Or would light just be emitted? Just a thought. More on FTL later, after my placement exams....

As for the annihilation between the really fast particle and the dead stop antiparticle... I don't know. I've never understood the whole increasing mass thing. What is this excess mass made of? For example, if I suddenly accelerated to a good portion of the speed of light, and my mass increased, would I still look like me, only increased in size (not counting Fitzgerald-Lorentz contraction, of course), or would I be covered in some sort of weird particle stew?

Warp is for wimps.

Oh, and the particle-really-fast-antiparticle anhilation problem: it would seem that there would just be more energy released, as the particle-antiparticle pair would anhilate, leaving the kinetic energy of the antiparticle without anything to carry it, thus being dispersed as some form of radiation.
