Trillions Of These Are Flying Through Your Body Right Now

The particles of the standard model are the smallest bits of matter we know of. They make up everything, go everywhere — they're even flying through you right now.
Some of them, like neutrinos, are so small that 100 trillion pass through the space within your atoms every second — and most of them keep going right through the planet.
You encounter one sextillion photons per second, most of them from our sun. This includes visible light and ultraviolet radiation, which is why you wear sunscreen.
