So here is another ruins-as-map hypothesis:
Somebody recently reminded me that 2.2 is titled the Guardians....protectors. And it got me thinking, what if the alien ruins is a map of the protective structure created by the Guardians, protecting SOL.
The hexagonal structure in the ruins represents protective points around SOL. SOL is the large "landing pad" and SYNUEFE XR-H D11-102 is the small landing pad
While the the small landing pad is not centred on the south-west corner point of the hexagon, I believe it only represents what is at the corner point (like a projection from the corner point). So when measuring from the large landing pad to the small landing pad you would measure to the corner not to the centre of the landing pad (see yellow line).
Now this also goes for SOL. I am thinking that the position of SOL should not be measured from the centre of the large landing pad but from a point on the hexagon's horizontal line, directly below the centre point of the pad. This would be a point pretty much on the northern-most point of the southern-most "clamp" of the landing pad. (another possibility is that SOL is at the centre of the cross formed by the two large ridges in the middle of the hexagon...a logical place for it to be, right in the middle of the protective barrier).
So I have a couple of predictions:
1) I predict that there are 5 more ruins sites to be found. Each one will be like the SYNUEFE ruins but with a different corner of the ruins hexagon with a small landing pad structure representing the world where the ruins are.
2) The things we collect at the sites have been left for us by the Guardians to help us in the fight against the Thargoids...(yeah, maybe this one is a little more obvious...in the "duh!" category)
