I was doing my usual poking around online, when I came across this webapge : a single Hydrogen atom, done to scale, to show just how much empty space there is in the universe.

The big blue dot to the right of the text is a proton, or the center of an atom.  The electron is the little particle that circles around the proton.  (This is the basic structure of all atoms.  Some just have more electrons, and more stuff inside the proton.)  This proton is is 1,000 pixels across.  The electron, is 1/1000th the size of the proton - or one single pixel.  And it just happens to be, to scale, 50,000,000 pixels away.  50 MILLION pixels away.  Thats 11 MILES of webpage.  And this web page is 50 million pixels wide.  49,999,999 of those pixels are completely empty.

From the creator of the website : “I recommend trying to scroll from here to the right a screen at a time,
just to see how long it takes the little thumb in the scrollbar to move
visibly. True masochists can try to scroll through the whole eleven
miles - but the scenery along the way is pretty bleak.”

It’s pretty amazing how everything we consider “solid” has so much empty space in between. . . .
