Yup. There are so many unanswerable questions in science and the universe. But that's what makes life so interesting. We can all be explorers and will never reach the edge of the universe. The macro and the micro are equally infinite. I mean, we can't figure out what's the smallest part of an atom is. We got past protons and neutrons and electrons and found quarks and leptons, but what are they made up of? That Hadron collider is trying to figure out what started the big bang and all that we see and don't see by smashing atoms. It's all interrelated and connected.
