A lot of us remember this from being kids, right? The fear? The uncertainty? The hiding under our not-radiation-proof-in-any-way desks? Being pretty convinced we’d never make it to adulthood?

While many of us have considered whether they’re “gonna drop the bomb or not,” have you ever wondered just how a full-on nuclear war would actually play out?

Well, some folks at Princeton University have. The Program on Science and Global Security (SGS), based in the School of Public and International Affairs, conducts scientific, technical and policy research, analysis and outreach to advance national and international policies for a safer and more peaceful world.

So it stands to reason they’ve also developed a simulation depicting how a nuclear war would unfold and what the cost would be to humanity.

The simulation depicts each phase of nuclear attack using real information, where attacks would happen, how many estimated casualties, and so on to illustrate the end of the known world, because that’s what it is.

Go ahead and watch if you can.
