Ok, I want to talk about Subspace. I've been giving it a good deal of thought, and I have some interesting models I want to mkae for it, but I figured I'd give my thought to the community, and see if they feel the need to comment, exapand, or change my ideas. Let's see what we can come up with, shall we?
First off, what is subspace? Well, the basic principal is this: subspace is the 4th spatial dimension. (We're going with the model of 4 spatial dimensions, and one of time.) The concept here is pretty simple. By bending gravity, we are tunneling into the 4th dimension. Now, the reason this makes space travel possible can be illustrated by this idea: take a 2 dimensional bug. Put it on a curved surface. Now, the bug will figure out that the shortest distance between two points is a straight line. However, if you limit it to two dimensions, the line chosen is really an arc in three dimensions. Now, let's give the bug the ability to move in three dimensions. The bug can now make the distance much shorter, by going straight in three dimensions. This is the principal of subspace. you are going straight in four dimensions of space, instead of the three we live in.
So, what are the rules of this dimension? Well, first off, it's tied closely to time, to 3 dimensional space, and to gravity. The fourth dimension is gravity's "home" dimension.. meaning, it unifies with the other three forces in this dimension. (I think that's accurate. Someone check this for me.) So, because of that, all objects in normal space have mass shadows in subspace. You should avoid those. Also, the entire dimension is littered with gravitational eddies that make navigation difficult, dangerous, and not for the faint of heart. (I will get to this in a minute.) Now there's two general rules about subspace. First: The deeper you go, the more 'straight' you can make your line, so the faster you go. (note: gravitational eddies, and the over all 'subspace pressure' increases as you go deeper.. and you need to generate a stronger gravitational field to keep you ship from going crunch.) Second: Anything you do in subspace (like explosions) effects 'normal' space. Hence, a bomb set off in subspace may cause shockwaves that bounce off the 'surface' (aka interface between normal space and subspace) till the gain enough energy to punch through, and show up in normal space as strong waves of gravity... something that could destroy planets. However, this is totally unpredictable, since no one can predict when the wave will hit normal space.
Now, something that's happened, is something much like subspace drives have been built in susbspace that smooth out most of the eddies, and make 'lanes' for ships to travel in, making travel faster, safer, and much more feasible. Keep in mind though, if you want to use the lanes, it might mean taking the long way around, since these lanes will only be to populare places. The military frequently sends ships to places with no lanes, and pirates frequently avoid them. (Less police). almost no one destroys lanes, since that would be shooting yourself in the foot. Subspace eddies have been known to destroy entire ships as large as a cruiser, in violent areas.
This leads me to an idea: weather in subspace. there could eb susbspace storms that make travel impossible, or something like that. It could be fun!
Now, the thought I have for subspace is basically a this nebula like environment, where you see something akin to lightening, and it gets much darker as you get deeper. Also, I imagine the interface to realspace to be a shimering, distorted place, lining the bottom of subspace. A mass shadow would look like a dark, twisted up knot of subspace.
So, what do you guys think? I wanna start work on this.. but I want to go in with a plan in my head. Also, ask quaestions, so I cna improve the website.
