What is 99.999% empty space?

9.999% empty space means that even though things seem solid, they're mostly made up of space where nothing is.

Imagine you have a big balloon full of air. It looks like it's filled with something, but really, there’s just air in there, and lots of empty space between the tiny particles that make up the air. Now think about a table, it seems solid when you sit on it, but if you could zoom in super close, you'd see that it's mostly empty space too!

Think of an atom like a big playground. The particles (like electrons and protons) are like kids running around, they're tiny, but there’s a lot of room between them. If the playground were as big as a city, the kids would be just dots in the middle of everything.

So even though something feels solid, it's mostly empty space, with only a few tiny things moving around inside!99.999% empty space means that even though things seem solid, they're mostly made up of space where nothing is.
