Being a lifelong Trek fan, I am still bewildered by the Abramsverse Trek films.
The use of the black hole created by the red matter apparently affects space-time much like the quantum rift from the TNG episode "Parallels" (7th season). Spock is not just thrown back in time, but also into another quantum reality. Unlike a parallel universe, as stated by Uhura in the film, the quantum reality would have the changes to objects like starship and uniform designs, character ages and origins, and even looks. This would also explain why Khan, who was born a Sihk warrior at least 150 years before any 'time change' that created the events in the film happened, suddenly became a scrawny white guy. It also explains why the design of Federation ships is so radically different. Is there anything out there that can give a good in-universe answer as to why so much has changed BEFORE the actual intervention of "old Spock" and Nero?
How this is supposed to play out canonically?
EDIT: Apparently, my question leads readers astray. What I want to know is this: Is there a canon-based reason for the dramatic changes seen in the Abramsverse?
