Sure, you think the world is full of solid objects. You think the radio you’re listening to is solid. You think the floor you’re standing on or the chair you’re sitting in is solid. Heck, you probably think that you yourself are a solid object. Wrong! One of the strangest things modern atomic theory has shown us is that what we commonly think to be the world of solid objects is for the most part empty space. That’s right. Even something as reliable as a table, a brick, a baseball, even your body, is by and large just empty space. Why Is That? It’s because you, the baseball, and everything else is made up of atoms. And atoms themselves are mostly empty space.
