Last time I recalled, Star Trek was science fiction. From some of the "technology" that I've seen in the first movie and the new one, it appears that this alternate reality has an unusually higher level advancement in technology than the prime universe. Theoretically speaking, it is possible that the envelope to certain limitations that were prevalent in the prime universe are no longer an issue of concern in this alternate universe. In fact, I do not think this was the prime universe to begin with because according to some current theories in time travel, it is not possible to go back in time to "your" prime universe. Instead, you can only travel to the past of another universe. This might explain why the new Kirk has blue eyes instead of brown, Spock and Uhura are a couple, Checkov has blonde hair instead of dark brown, and why all the ships are bigger and better. Pike was supposed to be in a wheel chair (according to the TOS pilot episode "The Menagerie"), and Section-31 is supposed to be an organization that nobody knows about and is never officially recognized or even spoken of until Deep Space Nine. So I would hold back with arguing about the technological limits that theoretically exist in a science fiction genre.
