If Carl Sagan taught us anything about our universe in Cosmos, he taught us how small we are in the grand scheme of things. The universe deals in magnitudes far beyond our comprehension: billions of galaxies, trillions of stars, quadrillions of particles. So many, that one crazy fan compiled all those 'illions into one trippy supercut.
The video's premise is very simple. It's literally every time Sagan says million, billion, trillion, or quadrillion on his seminal 13-part series — in order. At first, it's funny. Then, as you start to comprehend the incredible scale of numbers these big, it's just staggering.
Thanks to Sagan, though, many people realise how we shouldn't be scared of our impossibly huge universe. We should be intrigued. And we should be exploring it.
