To test this experimentally took some time. First, I had to find a Jove observatory system. Second, it also needs to have a set of thermoelectric convertors -Drifter-adapted Sleeper technology- primed to the hyperspace signature of Sanctified Vidette rather than another former Drifter wormhole. Thirdly, it has to be in a dormant state, not yet activated.
Finding a suitable set of convertors took a while... but I finally did. I was in communication with the Navy Anchorage in Sanctified Vidette, who record and monitor all wormhole signatures in Sanctified Vidette. When I was ready to create the wormhole K162 in Sanctified Vidette, I gave the signal, and then breached the V928 wormhole - hoping not to be trapped in some hyperspace pocket universe.
It worked. At the moment that I breached the V928 in G-G78S, a new cosmic signature QKB-168 appeared in Sanctified Vidette. The signature was an unidentified wormhole exit, out of which the Indagatrix emerged. A new wormhole was created in Sanctified Vidette. The hypothesis is corroborated!
Like every good research work, this gives rise to follow-up questions. Why do we now have to breach the V928's for the exit to appear, and not before? What turned those into more "regular" wormholes than they were before? How is that linked to the appearance of other hyperspace anomalies?
To that my friends at the Navy Anchorage add "How can we use this for defense purposes?"
