A random ideas thread, for Star Trek - all series and movies, even the ones I hate (that would be Abramstrek, and to a lesser degree, ENT, VOY, and Nemesis). When using an idea set in an official alternate universe, like Abramstrek, the Mirror Universe, or one of the ones from <a href='http://memory-beta.wikia.com/wiki/Star_Trek%3A_Myriad_Universes' target='_blank' rel='nofollow'>Star Trek: Myriad Universes</a>, make sure you specify which universe(s) you're working on.
AU from the timeline that existed for most of the ENT episode <a href='http://memory-beta.wikia.com/wiki/Twilight_%28episode%29' target='_blank' rel='nofollow'>Twilight</a>:
Some time after Earth is destroyed, the NX-01 travels back in time to the twentieth or twenty-first century, to change history by giving past-Earth the technology and historical knowledge they bring with them.
How far back they go is up to the writer, but I recommend far enough back to prevent WWIII.
