Every “what if”, explained second by second.

Welcome to Second by Second, the animated channel that takes one big “what if” and shows what would actually happen: after one second, one minute, one hour, one day.

What if the internet shut down for 24 hours? What if GPS went dark? We follow the chain reaction step by step, using real research, real outages and expert estimates. No made-up facts. When something is a best guess, we tell you.

Meet Zero, our tiny robot witness. Watch the light on his antenna: green = all good, yellow = trouble, red = disaster.
