I don't know if the ones on Salvation work the same as the ones on my ship, but Federation transporter technology dematerializes your entire body, stores a pattern of it, and then rematerializes it some place else. Sure, it lets you travel long distances and skip the middle step of actually covering that ground. Or space. But nobody's been able to really answer to my satisfaction whether or not the original you dies in the process.

It's all philosophy until you're standing on the platform yourself, you know. I'll use the system if I have to, but the possibilities are a good way to keep yourself awake in the middle of the night.
