So, you’re wondering how the big show ends, huh? Well, one day the universe will die. The big questions are: why, how, and will it stay dead forever? And how do we even figure this stuff out?

So, you’ve probably seen videos playing around with nuclear weapons, and yeah, there’s a weird sort of fun in watching stuff blow up. Seeing fireballs, shockwaves, and radiation – it’s fascinating, maybe a little horrifying. It can make you think about how much destruction we’re capable of. But those videos, while they show some of the power, don’t really get into what a real nuclear explosion means. It’s not just about big bangs or bright flashes, like with silly stacks of TNT. A real nuclear weapon is about you, and everyone else.

Imagine you were back in the 1980s. If someone told you then that computers would soon take over everything – shopping, dating, the stock market – that billions of people would connect through a kind of web, and that you’d carry a handheld device way more powerful than old supercomputers, it would sound completely absurd. But guess what? All of that happened. Science fiction became our everyday reality, and now we barely even think about it.

We’ve had a lot of folks ask us a pretty serious question: What would happen if we gathered up a giant pile of bombs and set off every single nuclear weapon in the world all at once? Funny enough, we looked around and couldn’t find a good, solid answer that really satisfied us. So, we got some scientists together to figure out the math and answer this super important scientific puzzle, for good.

Alright, listen up. There’s a war that’s been going on forever, billions of years even, killing trillions every single day, and most folks don’t even know it’s happening. The main fighter in this war, the single deadliest thing on our planet, is something called the bacteriophage. Or just ‘phage’ if you want to be quick about it.

Ever wonder what would really go down if we set off humanity’s biggest nuclear weapon way, way deep in the ocean? You might think, “For sure, we’d get tsunamis hundreds of meters high wiping out coastal cities, earthquakes leveling whole countries, or even new volcanoes causing a nuclear winter.” Maybe you even picture Earth getting ripped apart or thrown out of its orbit? Well, hold up – it’s almost the opposite of that, actually.
