Re: Is everything before the destruction of the kelvin exactly the sam
Exactly. If two alternate universes are essentially identical then why -wouldn't- essentially the same events, including parties traveling into the past of other essentially identical timelines, occur?
Similarly, it can be argued that there's multiple versions of the Mirror Universe. In some the Terran Empire is brought down by the Klingon-Cardassian alliance as per the televised episodes, while in others you end up with a "Dark Mirror" scenario where the Empire endures at least as long as TNG.
Or one variant of the Mirror Universe where the Klingon/Cardassian Alliance have cloaking devices; and another universe where they don't (The Emperor's New Cloak)
It's a FAAAAKKKEEE!
