14 billion years. That's how long the universe has existed. Voyage to the beginning of everything and witness the formation of the universe from practically nothing to the immense and wonderfully complex realm in which we live. Admire the simplicity of our solar system's formation and watch the Earth take shape. See life slowly, then suddenly, fill up our planet while being venturing the to brink of annihilation more than once. Examine the increasingly complex history of humans. Finally, glimpse the future of humans, Earth, and the solar system. "The Past Is the Key to the Future" is a chronological history of time, the universe, Earth, and life woven together in a beautiful tapestry of existence. Author Andy Epton brings his experience teaching astronomy and Earth science to print in his first book. The text is conversational so it feels as if he is talking to you directly and having a simple conversation about the wonders of nature. The content is complex but presented in such a manner as to be easily accessible.
