I'm referring to all those other things - the Xindi attack, the Borg in "Regeneration", the events of "Shockwave", etc. There is no evidence that those things didn't always happen. I don't care what Daniels says.
If everything depicted in "Enterprise" always happened, why did they have to send time travelers back to make sure it happened? That doesn't make any sense. The time travelers were blowing up planets and killing people in order to CHANGE the past. If they wanted the past to stay the same, they could have just stayed home.
When Lt. Yar went back in time in "Yesterday's Enterprise," she changed the past so that the new timeline would be DIFFERENT than her future, thus preventing the Federation-Klingon war.
When Admiral Janeway went back in time in "Endgame," and got the Voyager back to Earth 20 years early, that obviously changed the last three decades that she remembered from her original timeline.
And when the Borg went back in time to assimilate Earth in "First Contact," we know for a fact that Earth was not assimilated in TOS. The Borg went back in time to CHANGE the past, not keep it the same.
TOS took place BEFORE any of these 34 separate acts of time travel altered the past timelines depicted in "Voyager," "First Contact," and "Enterprise."
Not only is the "Enterprise" and "Star Trek XI" timeline different from the original timeline depicted in TOS, but Ambassador Spock and Nero are from the alternate timeline depicted in "Endgame" and "Star Trek: Nemesis" (where Janeway and the Voyager got back to Earth early), so the Ambassador Spock seen in this movie is from that alternate timeline, not the original timeline seen in "Unification, Part II," which itself was an alternate timeline, as evidenced by the presence of Commander Sela, the daughter of Lt. Yar, a time traveler from the "Yesterday's Enterprise" timeline. So the Spock in "Unification, Part II" is in a different timeline from the Spock we last saw in "Star Trek VI."
So the last three times we have seen Spock, each has been in an alternate timeline, plus the fourth alternate Spock played by Quinto in this movie.
In our modern understanding of quantum physics, there is, properly, no such thing as an alternate timeline. When time travel is involved it's really just shifting dimensions, they always end up in an alternate reality.
Yes, this flies in the face of everything we've learned about time travel from the Trek universe in the last 40+ years, but hey, there it is.
Everything we've learned about time travel from "Star Trek" over 40 years has been arbitrary and inconsistent. From a couple episodes, you might infer that there is only one timeline that is continually erased and overwritten like a blackboard (like in "Back to the Future"). But other episodes are consistent with alternate timelines as depicted in this movie, such as "Endgame." Plus there are many other examples of alternate realities, such as the Mirror Universe and all the alternate timelines depicted in "Parallels."
Obviously, the hundreds of writers who have worked on "Star Trek" over the years have just been making it up as they went along. There has NEVER been a time travel rule book,
This movie did not introduce anything surprising or new. It's just another time travel story that may or may not be consistent with past time travel stories.
