Dekker: Remember what I said about scale? You just demonstrated that you have absolutely no ****ing clue about it.
Locating cargo depots is easy, because all you have to look for is for subspace exits. The depots we've seen so far have all been in rather empty areas of space, away from big radiation sources like a sun. By putting something so near to a star, you can pretty much guarantee that any signal emanating from your position will be scrambled to hell. Yes, Daedalus is massive compared to anything else humans have put into space. But compared to the Sun, it is still less than nothing. Yes, it has an energy output. But compared to the Sun, it is negligible, and lost in the noise.
So, Dekker, please remember that we're playing by semi-realistic rules in BP, not the GTVA-Wankfest rules you want to have.
