Tens of trillions of neutrinos pass through your body every second.
Why this sounds fake
Your body feels solid, so invisible particles passing through it by the trillions sounds impossible.
Your body feels solid, so this sounds like science-fiction trespassing. It is ordinary physics. The U.S. Department of Energy explains that tens of trillions of neutrinos from the Sun stream through your body every second, and you do not feel them because they interact so weakly with matter. IceCube gives a similar scale, about 100 trillion per second. The exact count depends on what you include, but the point is stable: “solid” matter is mostly not a wall to these particles. You are being crossed constantly by something you never notice.
Solid-feeling you is barely a wall: trillions of solar neutrinos pass through every second.
