So the Star Trek universe is now in an alternative timeline. Everything that we ‘know’ of Trek’s future history (save, of all things, the _Enterprise_ series) has been wiped out, and our beloved crew (and all the writers tasked with coming up with new and interesting things to do) has a blank slate to work with. However, it’s still a pretty big universe, and there’s a _lot_ of stuff out there that won’t have been affected by the timeline split. While I’d rather see _new_ adventures from here on out, if writers ever need some inspiration, there’s a fair amount of stuff that we already _know_ is going to be a problem down the line.

So, with a little digging around on [Memory Alpha][1], I present a (_very_ incomplete) list of things that Spock Prime _could_ warn the Federation about, as they should still exist to pose future threats to the Federation. Obviously, one _could_ just list every bad guy and alien encounter seen in all the series and films, but I just wanted to grab a few of the ‘biggies’ (that is, major potential death toll events) that came to mind.

Feel free to toss out more that might be interesting, this is just a few minutes of pondering.

* 2267: Discovery of the S.S. Botany Bay, carrying [Khan][6] and his crew of supermen. Probably best to either just torpedo the ship, or aim it at a planet _not_ likely to explode and dump Khan and crew off there as if they’d arrived normally.
* 2267: The [planet killer][7] starts gobbling up Federation worlds.
* 2268: [Yonada][3] is on a collision course with Daran V. Perhaps not a threat to the entire Federation, but the Yonadans have the cure for the disease [xenopolycythemia][4] which will kill McCoy in 2269 if not treated.
* 2268: A giant toxic [space amoeba][8] which could multiply and ‘infect’ the galaxy appears.
* 2273: [V’ger][2] returns in search of its creator.
* 2365: First contact with the [Borg][5]. However, as this contact is instigated by Q, there’s no way to positively determine an exact date when the alternative universe Borg will discover the Federation.
* 2387: A super-supernova destroys Romulus (remember, that was only stopped in the Prime timeline, not the new timeline).

Update: Pop Culture Zoo has taken a [much more in-depth look][9] at the ramifications of the new timeline that’s well worth reading. Touches on some of the things I mentioned in the list above, and brings up a few others.

> Now that we know how the new Star Trek film handles the continuity issues, what exactly does it all mean and what are the greater implications to not just the original series, but the greater Trek mythos as a whole? I freely admit I may be the only one who really cares, but the more I started thinking about what this new timeline meant, the more it spiralled out of control. So, I decided to take a stroll through established Star Trek history and was surprised at all the events, large and small, that are affected as a result of two actions on Nero’s part. It all starts in the time of Mark Twain.
