Re: Time Travel method in Trek XI- possible
If I remember right, the slingshot that happened by accident in TOS was noted by the crew to be the first time it had ever happened. So the idea to do it in the movie is possibly against cannon. Now they might have come up with something else, the Nexus has been charted several times for example according to dialog from ST:Generations.
Somehow I doubt that we will really see the Nexus in the new movie. Nobody but fans would recognize it. And as Ronald D. Moore and Brannon Braga so funnily admit on the commentary track of GENERATIONS: The idea of the Nexus doesn't really make the slightest sense. So easily Spock could use it to stop Nero using it in the first place ...
Bashir: »Out of all the stories you told me, which ones were true and which ones weren't?«
Garak: »My dear doctor, they're all true.«
Bashir: »Even the lies?«
Garak: »Especially the lies.«
