So cool. Dark matter is called dark because there’s no electrical activity (ergo, light) and so it’s detected by its gravitational activity, which is pretty sweet. And if you think about the world with that logic then neutrons would be dark matter too, right, because there’s no charge so how could there be electrical activity? But, they have certain magnetic properties that may be detected so people think that neutrons are really just some combination of positive and negative charges that have basically a null sum of charge. I’m pretty sure a couple of studies have shown that. Science is freaking awesome.
