How the Edge of Our Galaxy Defies Known Physics

Dark matter makes me feel a little depressed, honestly. It's fascinating, but also frustrating to no end. Sometimes, the cynic in me wonders if it isn't just the "god of the gaps" clothed in  scientific jargon. On the other hand, I respect the fact that there is this honesty in the scientific community about what we don't know yet. That admission makes you vulnerable on the one hand, and shows integrity and humility on the other. I tend to believe them rather than those who claim to have it all figured out. Since I'm not particularly smart or highly educated, that humility and honesty is my guide towards truth.
