think small


Do you like ideas that can show our world in a different way compared to our day to day experience of it?

Ok, think small, really small. Physicist Brian Greene recently tweeted:

Remove all the space within the atoms making up the human body, and every person that’s ever lived would fit inside a baseball.

You’ve probably heard that stuff is mostly space. Stuff is just atoms, and they’re mostly space, lots of space.

Sticking with the baseball analogy, think of an atom’s nucleus as being the size of a baseball. Each electron would then be the size of the period at the end of this sentence and over a mile away from their baseball sized nucleus. So, imagine a period in a two and a half mile orbit around a baseball, atoms are mostly space.
