Chapter 4 was about the Birth of the Solar System. Five billion year ago a shimmering cloud created by an explosion began its gravitational collapse into a thousand new star systems. One of t the centers became our sun and its eight planets, a solar system. Earlier people couldn't figure out to formation of the planets and the sun and the moon. We are also seeking our path into the universe as awe discover more about the planets, their movements and their composition. We are living on a planet traveling around a star.

This game rise to many things such as the oceans, animals in the streams, and wolves the mountains. One of the most compelling concerns was the nested nature. The largest dynamic structure in the universe is thee galaxy. Over four and a half billion years the earth has moved toward ever greater complex and interconnectedness.
Chapter 6 was about Living and Dying. We remember that energy from our lives comes from original flaring forth of the universe, and the atoms of our bodies come form explosions of ancient stars, the patterns of our lives come form many ancestors over billions of years. We begin to appreciate the manner in which life remember the past and beings fresh forms today.                                                        In life we live and learn.
Chapter 7 was about The passions of Animals. Our passion is our urge to merge.

When lizards have evolved from their fish and amphibians, the passion to merge has deepen. With mammals, the passion reach yet a new crescendo. All animals live in the great drama of their passions. We live in a universe where choices are made. Not everything goes. Some things are better than others and are preferred. No matter how difficult it might be to choose one and reject the others, life insists upon it.
