Explore scientific questions, experiments and discoveries, with explanations of the evidence and methods behind what researchers conclude.
Science advances by turning questions into testable ideas, confronting them with evidence and revising what we think we know. Here is how that process really works—and why uncertainty is a strength, not a flaw.
