Unsolved Mysteries of Science: Consciousness

Why does the brain create a β€œyou”?

This series explores one of the deepest mysteries in science β€” consciousness. From the hard problem of consciousness and neural correlates to qualia, free will, integrated information theory, and the possibility of artificial awareness, we explore what it truly means to be conscious. Are we just biological machines… or is there something more behind the mind? 🧠✨
