What Do Alien Civilizations Look Like: calm curiosity about space
Kurzgesagt's trademark calm, animated explainer, this time asking how big a civilisation could get.
Kurzgesagt's exploration of alien civilisations scores 90/100 for settling a wound-up child and a perfect 100/100 on educational value, a genuinely rare combination of calm and substance. Explorers hit a perfect 100/100 at ages 8 to 11, and Independents aren't far behind at 95. It's a great pick for a curious, focused mind rather than an active, physical one.
