Re: Is the "Yesterday's Enterprise" alt-timeline the REAL one?
My pet theory is that the JJverse flows from the First Contact/Enterprise universe, created by the Borg incursion. The monster ships and seemingly accelerated technology is a consequence of Federation scientists dissecting leftover Borg tech, and a much more powerful Section 31 pushing a beefed up Starfleet to protect Earth from the horrors they know are waiting for humanity.
First Contact and ENT are part of the existing timeline. They're not a new one. They were always supposed to happen.
And both are common to the prime and Abrams timelines.
There will be order.
