Okay, so at the risk of drawing us in a full circle. @knowles2 is right - it's supposed to be pretty obvious, and I'm pretty sure we're all intelligent folks (not sure about Kerrash tho, right) - so what is the simplest explanation?
The facts are on the wiki, of course but in terms of behaviour - it:
- Makes an alien/insectoid sound
- Taps out (or rather gurgles out), in Morse, the name of the local body or system, depending on proximity to the nearest body.
- Expires in line with all other dropped cargo, except it does have a unique animation for this (and sound)
- Does corrosive damage to the carrier's ship
- Can only be found being transported in human convoys
- The pilots in the convoy don't know what it is
- ...and don't appear to have been well-prepared for carrying it
-...and the places where these convoys are found doesn't seem to centre on any one particular area (does everyone agree with this?)
- Looks like it contains 'something' or a lot of 'something's
- Is surrounded by fairy-like sparks that move a bit like flies when viewed from a certain distance
- Causes visual distortion when viewed from a certain distance, specifically, it blurs the objects that are behind the UA from the observer's POV
So, again - ignoring all the tests that have been tried, all the theories that have been put forward. Based on this information alone, what *is* it? Most logical answers please - and let's see if we can't come up with next steps from that. If you'd humour a tired 'scientist'![]()
I don't have much to add here, but just want to question the "insectoid" aspect of the sound. Han Zen has shown pretty well that it is whales, sea turtles and dolphins I believe? Nary an insect to be heard. I think we jumped to that conclusion with the chittering way back at the start and the possible Thargoid connection, without any real basis for it. We don't even know what sort of sounds Thargoids make.
I am out of ideas as mentioned, but will give this some more thought and hopefully more will come in direct proportion with the amount of alcohol consumed this evening.
I did a couple of minor wiki updates adding some of the additional theories and the suggested Morse test (playing it back to the UA in local comms).
