Two years ago, twelve-year-old Emma Hartman and her father, Gary, were part of a larger family. But Emma's mother and two siblings died in a tragic accident after a camping trip in the mountains of Colorado. While her dad tries to rescue the three from the car, Emma witnesses three beautiful sparks lighting up the sky. Itamar Pitowski is a visiting professor of philosophy and physics at Princeton University. He delivers an introductory lecture about what is known about the universe, and he answers some burning questions about religion and physics. Walter Crondike, a news anchor and investigative reporter, receives an unexpected visit at the office from Brian Landy, a young man claiming to be an angel who has a message to deliver from God. Through Emma, Itamar, Walter, and a slate of other fictional characters, Speculations about God and the Cosmos tells a story about math, science, and speculation. Narrating a tale of heaven and earth, author and mathematician Stan Gudder attempts to answer some of the big questions that have occupied the thinking of mankind for thousands of years. These questions have remained unanswered, but because of recent advances in math and physics, many are getting closer to their resolution.
