Where can we human beings find our future? Will the God give us the answers? For somebody, it's true. But for the whole mankind, I don't think so. Because creators vary from different cultures. How could many creators lead us only one future? But we know that mathematics and physics are exactly same in different countries. And of course, the appearances of mathematics and physics, equations, are almost same. So why not explore the future in the sea of equations? This fiction does want to demonstrate it.
