Really Small 
Friday June 23, 2006 by Hal
I’m always trying to find metaphors, illustrations and allegories for the size of the Universe — both great and small. As I think I’ve blogged before, on a scale from smallest subatomic particle to the complete Universe, a human being is about halfway.
Which means that looking out at the cosmos (in your imagination), is the same as an electron “looking” at you!
But today’s mind-blower is this illustration of the relationship between a proton (subatomic particle in the center of an atom) and it’s electron (subatomic particle ‘orbiting’ the proton).
In this illustration you’ll see a blue sphere representing the proton that is 1000 pixels across — to reach the electron which is ONE pixel across you’ll have to scroll to the right the equivalent of 11 MILES!
Makes the mind boggle doesn’t it? Everything that seems solid is made up of mostly empty space. Meditate on that for a while!
