Re: Do FIRST CONTACT & "Little Green Men" still happen in the Abramsve
I rather liked the Guardian and the concept of Temporal Shielding (although not its application). The Nexus not so much. If they were allowed to use the Guardian again, I wouldn't mind them breaking the rules but casual time travel with the intent to change history is very tiresome and quite illogical.
I hate the many worlds theory precisely because its mechanics are so messy. Once the 'event' takes place you can NEVER get those characters back to their original timeline.
Unless you encounter some typically convenient sci-fi plot device such as alien technology or a phenomenon which allows travel between the different universes/timelines. Something similar to the Nexus or the Guardian.
If the viewer went back to the original timeline the event would not have happened in the first place.
That sounds like you're trying to argue against MWI by using the traditional paradox-laden baggage of single timeline ( which would not be applicable ).
