This particle is flying through your body trillions of times every second completely unnoticed

[00:00:00]Japan built Super Kamiokande, a detector buried under a mountain inside a tank 13 stories tall, filled with 50,000 tons of water, and lined with about 13,000 sensors waiting to catch a particle that almost never interacts with anything.

[00:00:12]Meet the neutrino. It's a tiny particle.

[00:00:14]Trillions go through your body every second, but they almost never bump into anything, so they can fly straight through the whole Earth like it's not even there. Here's the part nobody talks about. Out of all those trillions of neutrinos going through that tank every day, only a tiny few actually hit something, and when they do, [music] they make a little flash of light. In the 1990s, those little flashes showed scientists something nobody believed was possible, that neutrinos actually have weight. That discovery won the Nobel Prize in 2015. Here's where it gets insane. According to the math, when the universe began, matter and antimatter should have completely canceled each other out, leaving nothing, no stars, no planets, no us. And scientists think neutrinos may hold the key to understanding why matter survived. But the craziest part, every single second of your life, the particles that may explain why you exist at all are passing straight through you, and you will never feel a single one.
