And the one number I always have in my mind is that the Large Hadron Collider at CERN, the protons go around the ring, which is 27 kilometres in circumference, and they go around at 99.999999% the speed of light, so close to the speed of light. At that speed, distances shrink by a factor of 7,000. And so that ring... is something like four meters in diameter to the protons.
