The Self-Centered Universe: Living as the Main Character in a Simulated Reality is a groundbreaking philosophical manifesto by Richard Sweeney that challenges everything we think we know about existence. Blending metaphysics, quantum theory, consciousness studies, and simulation theory, this book explores the radical idea that reality is not a shared stage but a first-person, observer-dependent simulation rendered individually for each of us.From the double-slit experiment to déjà vu, from NPC theory to symbolic rendering, Sweeney guides the reader through a lucid framework where thoughts, emotions, and intentions are not reactions—but inputs. Reality is not fixed. It's programmable.This is not a self-help book. It is a self-awareness explosion.Whether you are a seeker, a skeptic, or a philosopher at heart, The Self-Centered Universe will awaken something ancient behind your eyes: the realization that you are not inside the world—the world is inside you.
