Carbon nanotubes. They're the darkest thing known, absorbing around 99.96% of all light. This absorbed light turns into energy. Now imagine that on an extremely large scale. If we could make something that absorbed all light, we could possibly make bombs made of absorbed energy. This is small scale of exactly what they think the big bang may have evolved. I could be off, but I want to try to provide some example of how something possibly [i]could[/i] come from "nothing".
