Re: Is everything before the destruction of the kelvin exactly the sam
(shrugs) I'm perfectly happy with the theory that time travel into the past always involves jumping to an alternate timeline, but in most cases the timeline is so similar to the one you left as to be essentially the same.
"Parallels" even establishes how you can determine whether you're in the timeline you started out in and one way you could return.
