Whale done... wah wah wah waaaaaaaaaaaaaaaaaaaaaaaaah
These seem like very practical assumptions. While I lean toward the idea that a random system was chosen, I also lean toward FD choosing Pleiades specifically because (IIRC) it's the closest Nebula outside the bubble or, at least, a prominent nebula. It makes sense.
What confuses me is the pattern of the systems with station malfunctions. I checked
here and the pattern seems somewhat inconsistent. If players are indeed using UAs to sabotage enemy systems, why hasn't Achenar or Alioth been affected? Or any other capital of each power?
The only answers that really come to mind is that perhaps black market value increases in more distant systems from where the UA is found. Is the UA price uniform throughout all stations? Or do they have varying values? If this isn't known, I'll be willing to test this.
(Less practical thought here): Also, if the UAs may in fact react to certain chemical elements, would the gas in the Pleiades Nebula be comprised of anything that might effect the UA? Or could the UAs be giving off a gas similar to what is in the Pleiades?
One more thought- maybe the UAs are giving off a type of exhaust produced from using something for fuel. Considering that the UAs distort stars behind it, it would have to be putting out either a form of exhaust (heated gas) or it's distorting the space-time around it.
Anyways, just food for thought. I just hope it's productive thought
