Billions of invisible particles pass through you every second
Trillions of nearly undetectable neutrinos, originating from the sun and beyond, pass through your body every second, offering a unique window into the universe's hidden workings.
Every second, an estimated 65 billion solar neutrinos silently stream through each square centimeter of your body. These tiny, chargeless particles, born from nuclear reactions like those in the sun, interact so weakly with matter that they traverse entire planets unnoticed. This ghostly passage offers a direct connection to the cosmos, carrying pristine information from distant events. Scientists use these elusive travelers to understand the sun's core and even ancient supernovae. While most neutrinos evade us, rare interactions in massive underground detectors have confirmed their oscillations, reshaping our understanding of particle physics.
