I was daydreaming about the UA research and thought I'd try going back to first principles.
The UA appeared with the 1.2 update.
We also got Hafnium 178, Painite, AI Relics, Antiquities, and Military Intelligence in the same update.
From what we can tell, the UA is either a sensor, a scanner, a beacon or an engine. The design would make it appear alien in origin, but it repeats nearby celestial objects with their english name in Morse code.
What is Painite?
An incredibly rare borate mineral that appears as orthorhombic crystals (hexagonal cross-section).
What is Hafnium 178?
Is a nuclear isomer with the potential to unleash enormous quantities of gamma radiation. What Googling Hf178 shows (and isn't in the object description) is that the gamma radiation is coherent, ie. it has a sharply defined frequency.
SAP8 Core Containers showed up later.
There is now a mission for Elite explorers called "Obfuscation On The Outer Rim" where we discover some crystals of unknown origin could hold galactic coordinates, like a map. We are also introduced to The Dark Wheel providing them for study.
Why is Painite so sought after? It fetches prices in excess of 36KCr/t which is WAY above what an ordinary mineral should cost.
I suggest that Painite is the material of the unknown map crystals.
I suggest these "encoded" crystals are the crystals stored inside SAP8 Core Containers.
So we have the following...
Unknown Artefact - FSD/engine?
Hafnium 178 - energy source?
SAP8 Core Container - map?
Painite might fit in here as well. Remember the bit about borate? Boron is used as a neutron moderator in nuclear fission reactors. It might slow the reaction down from running away with itself.
That's my reasoning. Now for the experiment proposal.
We need someone to carry an Unknown Artefect, Hafnium 178, SAP8 Core Container and Painite in their hold at the same time. Note any change in effects (damage rate for example).
Then eject all 4 items into space so they are in close proximity to each other and note any changes.
My thinking is that the Hafnium 178 is the energy source or "fuel", the UA is the "engine", the SAP8 Core Container is the "map", and Painite would be the "brakes".
We've tried UA in combination with the individual items before, but not with all of them at the same time.
