I prefer the alternate quantum reality theory (seen here
), for that permits the future exploration of the 24th and 25th centuries. Not only has this theory been incorporated to permit ST:Online, but statements from the ST11 screenwriters indicate that this was their intent -- they point to "Parallels" for inspiration for the time travel.
Sorry to rain on your parade, but I wouldn't want you guys parading your Prime Timeline disrupting theory without a counterargument logged.
With the exception of the two Ent timelines in that image (They should be one and the same), I thought that WAS what the image here stated. The First Contact timeline should probably be offset in relation to the Prime one, but because the changes werent all that big to begin with (up until Nero's incursion) it "fit" in with the original timeline very well.
