It took a while for the station to be moved piece-by-piece to a different location. As the procedure took place, every time about one third of the station was successfully transferred outside the sector, one of the flotillas generated some very anomalous wormhole - ones that seem to temporarily defy the laws of space-time - and disappear into it.
One of the navy ships made a note to try and capture this phenomenon when the last piece of the station was successfully jumped out of the system - for the last flotilla, of course. Sure enough, they exited through the same set of wormholes, and the ship saved a video capture midway through the phenomenon. It was a risk, for sure, but it didn't seem to result in any bad consequences.
Initial speculations of the phenomenon before the review were that since the laws and forces of such an "alien" travel method would surely rip apart and atomize any vessel that enters through it, there must have been some way these Theta-Icoveo ships are able to withstand it somehow. However, when studying the video feed closer, the ships seem to slowly atomize and break apart when nearing contact with the wormhole, but at such a close range it seems from the naked eye that they would be travelling through it. Everyone questioned why the Theta-Icoveo aliens would use such a drive if they knew it would destroy them in the process.
It took one keen eye from a quantum physicist professor to notice that at the very last moment, those "atomized" pieces begin recombining into a part of something else before going through the wormhole completely at the next instant, signifying that the breaking apart of the ship hulls was actually controlled, and bringing about the speculation that these ships undergo a sort of metamorphosis to adapt to the new environment of presumably yet another dimension, and the rulesets of space and time within said dimension. How they manage such a feat, however, remains unknown.
In the end, the Theta-Icoveo aliens kept their word, and the Tau combine's higher echelon managed to learn something new ((I presume the Navy had enough sense to keep this discovery under wraps?))
