Star Trek: 10 Most Mind-Bending Spatial Anomalies
3. The Nexus
Or the 'I Wish It Could Be Christmas Everyday' Anomaly
As we saw in Star Trek: Generations, the Nexus is an anomaly that doesn't merely mess with time and space — destroying ships and planets in its wake as it cuts a path through the Milky Way — it also screws with the minds of anyone unlucky enough to encounter it. Everlasting bliss wrapped up in a blanket of pure joy might seem like an enticing prospect, but if you surrender to it, it will drive you to obsession.
We don't know what Soran — the exact opposite of a good listener — experienced exactly when he was inside the Nexus, but it must have been damned good as he was willing to scheme and slaughter his way back to it. As member of a species with lifespans of countless centuries who apparently only age when they want to, Soran sure was overly tetchy about the possible ravages of time.
The whackiest part of the Nexus anomaly has to be Jean-Luc's 19th-century-style family Christmas with a remnant or "echo" of Guinan as a surprise dinner guest. Guinan is both on the Enterprise (D and B?) and in the Nexus at the same time. How the Nexus does all of this is never explained, but at least Guinan didn't go Soran-level insane in the process! And if Kirk could have gone back to any point in history upon leaving, why didn’t he make it a flippin' Tuesday?!
