After some kel-no-reem, I've revised my theory about Subspace.
See, it's like duct tape.
Stargate has subspace. Star wars has subspace (IIRC). Star Trek, hell, every other mission in Voyager was about subspace.
Does Babylon 5 or Wing Commander have subspace? I suspect they do.
See, subspace is the glue that ties everything together. And in subspace, an odd conglomeration of physics are used. This is why there can be no shields in subspace, and why it took so long for the GTVA to figure out how to track ships - they needed a combination of four different types of sensors to detect anything.
Some of you may recall seeing pictures of Star Trek warships in Freespace. How did they get there? There's only one way they could - subspace. Because everyone knows the FS2 engine doesn't support warping yet
.
I rest my case.
