:: The tone sounds like I'm being harsh (i.e. "stupid scientists!"), that is not intended. Any developer understands that the "actual fix/solution" often looks "really obvious/simple". It doesn't mean the developer who spent weeks to get to that elegant, perfect, implementation is stupid for not having thought of it in the first few hours of development... Something's been bothering me and for whatever reason, the term "Gravitomagnetism" has come up, oddly, several times in the last two days. Oddly because this paper was the start of it. Two days ago I was repairing a brushed DC motor and started thinking about magnetism more generally, which made me realize I've "forgotten" what little fundamental knowledge I used to have about magnetism. My first search was to search the relationship between gravity and electricity[0]. And after a mess of reading, I happened onto a pretty poor set of explanations about what the term "Gravitomagnetism" meant and after a lot of reading, I wasn't entirely clear if that gravitomagnetism was mainstream or crackpot (partly due to fascination reading those Air Force patent articles reducing the amount of time spent actually learning something). I'm guessing there's an obvious answer and my ignorance of the subject is at fault, but as I read about Dark Matter, it feels like an "excuse". Going simply from Wikipedia[1], "Observational Evidence", the evidence for its existence starts off with something that can be casually paraphrased as "Given our best understanding of how things should work, when we actually measure how things are working, we find the numbers don't work, so 'Dark Matter'." And as you get further down the evidence list, you start to find things like "why there's so much of it" (except where in the heck is it all?) and why Galaxies are important for observing it. I know my mind is probably polluted with outdated (and, let's face it, probably often bad) information from various reporters covering a subject they know less about than I do (and that's not saying much), but as I read that over, I kept thinking "it really sounds like an idea that is better explained by something else". Am I completely off, here? [0] Which led to a bizarre hoax called the Hutchison Effect, several Quara articles of various quality, and all of those weird Air Force patents (due to another questionable 'effect' named after its supposed identifier).
