Very interesting post. To me, it’s all even more unexplained. The idea that there isn’t enough visible matter in the universe to explain what we observe is based upon the assumption that those very fundamental principles that we observe and believe (e.g. that mass attracts mass, like charges repel, opposite charges attract, etc.) are operative everywhere. Are they? We don’t even understand how or why mass attracts mass. We developed atomic weapons based upon release of ‘strong forces’ that we know exist, but the nature of which we don’t understand. We are, at this point in human history, only a few steps into a billion mile journey trying to learn how God works.
Can't argue with that. As to the laws of the universe being the same everywhere, check this out. It's going to blow me away if someday they show that the laws of nature on the far side of the universe are different than here on earth. The universe is strange, but so far it doesn't appear to be that strange!
