It was not easy to bring down the gravimetric analyzer, the thing is heavy and cumbersome. It took dr. Nahrami's team the better part of a day.
In the end, it was the right choice: it revealed the nature of the anomaly.
The discontinuity of earlier measurements at this boundary are real. Whatever lies behind the barrier has been cut out from our spacetime, and the remaining hole has been closed by stitching front to back via hyperdimensional folding.
In layman's terms, it is a cloaking device that works by bending spacetime around what you're trying to hide. If you try to poke it with a stick, the stick comes out the other end, probably some hundred meters deeper. That comes with some spatial refraction, which would cause the stick (or a drill) to break off. The stuff that lies in between can no longer be reached from our own three spatial dimensions.
I have never seen anything similar - this type of technology is beyond what we have. I can only think of Jove or Talocan who would master enough of spacetime and hyperdimensional engineering to create something like this. And doing this not in the void of deep space, but on a planet... perhaps it is this which caused the cataclysm?
After brainstorming with some friends who are much better versed in hyperdimensional gravity than I am, we decided that perhaps the closest analogy we have seen are abyssal deadspace pockets. With their help I will adapt an isolated dimensional thread from an abyssal filament to see if we can access the space that was cut out from Gammel XI.
Meanwhile, Mr. Firth will contact the Ministry - not my own preferred course of action at the moment, but he insists this is the right thing to do.
I am also a bit worried that there is at the moment an increase in Triglavian activity in the system. Dr. Nahrami tells me that during the Triglavian war, the invaders had a minor victory in Gammel and now still keep an active presence, but he concurs that there seems to be a spike in activity over the last couple of weeks.
