Most of reality is empty space. That's also true inside actual atoms.
I really think that human beings understand quantities up to about 10 pretty well. Above 20, things get vague and swimmy. At 1000, we're foundering. At 1,000,000, we're sunk. A million of *anything*.
It's not only true of distances, it's true of all numbers. Like odds. Everyone understands 10:1 odds. No one understands 1,000,000:1 odds. If they did, they wouldn't play the lottery.
We understand numbers that we can count on our fingers and toes, distances that we can see, heights of trees that we can climb. Beyond that, things get difficult. We can figure it out with arithmetic, but we don't *feel* it. Our intuitions about large numbers, long distances, and great expanses of time tend to go awry.
With that in mind, here's a map of everything. Everything is pretty big, so the scale is logarithmic. And if the typeface is too compressed for you, here are higher resolution maps. Warning: Everything loads slowly.

文房具 == bunpougu == (noun) stationery
Left/upper radical is 'door' (戸), which here means 'partition'. Right radical is 'side' (方). This character originally referred to a room partitioned off the side of a larger room. Henshall suggests as a mnemonic: 'Door to one side leads to wife's room.'
