What if science and faith are not rivals but twin witnesses to the same truth? In The World After Fire, Sergiu Margan--author of The Redemption Optimization and The Moral Kernel Optimization--argues that the deepest logic of the universe is neither blind mechanism nor brute mystery but coherence: the self-correcting harmony of love, freedom, and humility. Drawing on his own published mathematical frameworks, Margan shows that evil is not an eternal empire but a transient learning-cost, and that the moral arc of creation bends toward the perfection Scripture promised and mathematics confirms. From Genesis to Revelation, from entropy to resurrection, the book traces a single unbroken thread: every fall carries the seed of its own correction, and every act of mercy moves creation closer to the day when harm finally reaches zero. Written in vivid, accessible prose for thoughtful readers of any background, The World After Fire is a closing statement in the Canon of Coherence--a sustained demonstration that the gospel is not only spiritually compelling but structurally inevitable.
