The product of research around the globe and interviews with dozens of prominent scientists, God's Equation discusses the latest developments in cosmology, the study of the nature of the universe. Using Einstein and his theories to explain the links between relativity and cosmology via Einstein's "cosmological constant," Aczel tells us it is almost as though Einstein were God's mouthpiece, revealing the most fundamental truths about our larger environment, truths scientists are just now confirming. And yet Aczel reveals a side of Einstein - the man - no one else has brought to light. Aczel is the first to have translated certain letters of Einstein, in private hands until recently. These letters cast a new spin on Einstein's relationship with other scientists and his early efforts to prove his revolutionary theory that a strong gravitational force will make light bend.
