What an intriguing puzzle this is, have been thinking about this mystery far too much over the last few days and kudos to everyone who has tried anything and everything to unravel it. I've unsurprisingly not read everything so this has probably been mentioned before, but just in case it hasn't... has anyone tried taking a UA or SAP-8 wossname to one of the Voyager probes yet?
Just had another thought, although I'm not sure anyone would want to risk it on such rare items - "shooting" is one of the tests done, but what exact weapons have been tried? Lasers surely, but what about cannons, railguns, missiles, plasma accelerators or mining lasers? And what about the new power-specific weapons? The Cytoscrambler would probably be the safest thing to try, any filthy courageous pirates in line to unlock one in the next few weeks?
