No!. But Maia could be the bridge that combines the two by lens focusing. If the space station diagram is telling anything. It wants us to focus on something to make it appear. That's for sure. But what how and why none of us can find atm. Your crystal ball explaination is also prob part of that or there is a tiny galaxy out there confined to an orb or using a blackhole as a telescope to zoom in on a orbital celestial body. If anything it might be trying to show us how to combine Point A to Point B to make Point C That is A & B Combined which prob forms a wormhole asset cleverly assigned a blackhole poi and everyone is just flying by it like herpmah derps. I choose Maia because its part of 3 unique Thargoid Territories. Witchhead , Pleides, California that form a triangle tilted on its edge. I also find it odd that Palin's old engineering Base in Maia is still active with nobody home but the service robots running it. But Back to Maia. Using Maia's blackhole as a telescope I found Struve's Lost Nebula which I forgot was in the game cause it's so small of a nebula it rarely renders on the galmap it is not that far from the blackhole. So that's a thing. T Tauri/ Hind Nebula is interesting too as its not quite the center of the triangle but close enough with an interesting skybox. This Next one is interesting as it amplifies the crab nebula. Funny enough it has a space station named X. Could X mark the magic spot we been looking for? If you get the crab nebula oriented correctly and not by the galmap it almost looks like the spooky green space the thargoid portals show. It amuses me that Maia makes for a very good telescope in game. Unfortunately Due to recent events I am kinda focus around Polaris right now. So If I find anything interesting using maia again it'll prob be awhile. I am still cataloging Skybox constellation's too while by Polaris.
Possible. However, I've played to death with black holes and their lensing lately thanks to NGC 7822. The practical behavior I don't believe would actually allow it, so if there were any wormhole mechanisms in play, it would probably require a little more than just straightforward lensing. And I'm sort of doubtful that Thargoids would actually care because they seem to have vastly superior hyperspace travel tech, so not sure what they would black holes for.
From practical point of view a few observations I had were that:
1. If you're thousands of LS (not LY) away, you can see the "traditional" lensing - i.e. they act like a convex lens, with a caveat that the distortions are rather awful so getting anything useful by combining two is extremely hard. Their "focal distance" tends to be some multiple (or fraction) of 10k LS. Once you're out of the system, there is absolutely no visible effect of their existence. And as a little tidbit, neutron stars have the same lensing effect as black holes (from a distance).
2. Their gravitational influence is very limited - you won't fall into one unless you are VERY close, they have barely any pull at all if anything - I think there is some gravity field but it's very weak compared to even average planet.
3. As you get closer things get worse, similar if you stick your eye to the surface of a magnifying glass. You wind up drastically expanding your field of view, so in practical sense things get smaller, not larger.
4. If you cross the event horizon, it actually turns into a concave lens. You can't use it to magnify anything at that point.
Note that IRL lensing with black holes generally involves supermassive black holes at the center of galaxies. All those images with lensing effect generally involved some extremely heavy SMBH in some galaxy, and galaxies behind it that were literally billions of light years further (just like a lot of quasars IRL are black holes in very distant galaxies - not to be confused with pulsars which are a completely different thing). Here is the first one we found:
en.wikipedia.org
From the scientific point of view, the small ones are more or less useless for anything of the sort. Theoretically it could do something, but I'm not sure anyone observed them to do anything. Funnily enough, you don't need a black hole to get lensing - IRL the first observed light bending effect was around our own Sun, during an eclipse (and that's how the theories around gravity bending light were confirmed).
The theory that they can form a tunnel due to paired lensing is interesting, but you need extra tech to do anything with it - it won't just happen by itself. They are sort of completely wrong "shape" to form a wormhole. It's interesting that the game simulates the event horizon for them and it's actually quite far from their "surface", and that there is "normal" space inside and that the space is somewhat small; the main theory we have about black holes is that crossing the event horizon would basically take you to a parallel universe - assuming you could actually cross it which isn't particularly clear because time dilation goes to infinity as you approach it. For that reason, we're not actually even sure our models of black holes are correct, because theoretically nothing can actually fall into the ones that we can model normally. If we assume that there is some tech to do this, there is nothing to assume that some particular pair of them is better than any other. I'd imagine with that sort of tech you could drop into any of them and then navigate to any other, perhaps with some distance limitations, unless for whatever reason the tech would require them to be somehow "matched" - maybe similar mass or something like that. I've not observed so far black holes to give you any special ability in terms of making hyperspace jumps. You can drop into one, plot a jump somewhere and execute it just like anywhere else in the system. Also, they obstruct the destination just like any other object in space. Other than the fancy skybox show, and the pseudo-star in there, they don't seem to do absolutely anything special. If you wanted to tinfoil them somehow, you could try to do something with them with the Trinkets of Hidden Fortune and similar stuff, but I assume that's been tried.
If they were anywhere close to the "supposed" physics of this, dropping past the event horizon should bring you to a mirror galaxy.
Regarding Thargoids, they don't seem to have a need for them as they seem to have vastly superior ability to stay and travel in hyperspace. The charts have Merope, not Maia - I'm not sure that Maia is a particularly special system for Thargoids. It seems more special for us as an outpost in Pleiades.
If there is something about black holes and Raxxla, my personal bet would be for some planet to be "cloaked" as a black hole. If you were to invent a planetary scale cloaking device, it would probably appear like what we have in game as a black hole, honestly. But since it's fun to basically stick your ship's nose to them, I tend to drop into every black hole that I find, and I've never run into anything special.
