I loved the DA:O. 4 playthrus. DA:A, I was ok with. 2 Playthrus. DA:2 does seem "dumbed down" as you put it. If it doesn't get better soon (in spite of it's horrible combat system), it's going in the "did not finish" pile.
It could be the lack of comments is because everyone is too busy playing DA2. (but I think your guess was closer to home)
Neutrinos? (from the wikipedia page).
I don't think it's totally ridiculous to assume that different particles with different magnetic moments were affected differently by the immense magnetic field of a magnetar. But if the Gamma, Xray, and radio waves arrive within seconds of each other, it's hard to imagine another particle could've made the trip 1.5 days quicker. But maybe that's just my lack of imagination and poor math skills.
