For nearly a century, the Big Bang theory has stood as our premier framework for cosmic origins. It describes a universe that emerged from an unimaginably hot, dense singularity approximately 13.8 billion years ago, subsequently cooling and expanding into the vast web of galaxies we observe today. This is not a story of an explosion into pre-existing emptiness, but the dynamic stretching of space-time itself. By uniting general relativity with observational astronomy, scientists have reconstructed this history with astonishing precision. From the relic glow of the cosmic microwave background to the precise ratios of primordial elements, the evidence paints a consistent portrait of a living, evolving cosmos. Yet, at the very boundary of time, our physics falters, leaving us to wonder what lies beyond the horizon of genesis.

No AI help here — no suggestions, no autocomplete, nothing finishing your sentences. That is deliberate. Working out what you think is effortful, and the effort is the part that changes you: reasoning is trained like a muscle, and a muscle that is always carried gets weaker. Let something else do the thinking and you keep the answer but lose the capacity to have reached it.
