Re: Is everything before the destruction of the kelvin exactly the sam Both Nero and Spock were already caught in the black hole and thus protected from the changes that occurred when the Narada went back first. If you don't accept that, then First Contact too wouldn't have worked; there the Enterprise was caught in that time vortex/hole and protected from what the Borg did, while the whole universe they knew was replaced with that Borg-ified one. City on the Edge of Forever too wouldn't have worked if Kirk and Co hadn't been protected from the changes McCoy caused. So, my idea may be convoluted and complicated, but it makes some (Doctor Who-style of) sense and could give an explanation for the already apparent differences before the Narada destroys the Kelvin. God, why couldn't they have made a straight reboot. This would have spared us all this convoluted shit.
