How does Alan Lightman explain the concept of the multiverse in "The Accidental Universe"?

• Multiple Universes Theory: Lightman discusses the idea that our universe is just one of many, each with different properties and laws.
• Scientific Basis: The concept is supported by theories like eternal inflation and string theory, which suggest the existence of multiple universes.
• Philosophical Implications: The multiverse challenges the notion of a single, self-consistent universe and raises questions about the nature of reality and our place in it.
• Impact on Physics: If true, the multiverse would radically change the style of fundamental physics, limiting our ability to understand the universe from first principles.
