What forces molded the universe? Are those forces still at work, removing, changing, or adding heavenly bodies even as we gaze upward? Will humanity, and Earth itself, one day be gone? Are we alone?

We've all asked ourselves whether there is any meaning in human life. But for philosophers, this is just the first question of many: Is such a question even answerable by philosophy?
