And if you took out the empty space, you could fit your body inside a tiny cube which measures one 500th of a centimetre on either side. But the really weird thing is that most of the atoms are empty space, just air or nothingness.

Did you know that only about one tenth of the cells in your body are really you? The rest are bacteria.Ī: No, of course you are you, but you also have millions, or trillions, of bacteria in you.Ī: No, they're mostly really helpful.
A: Hey, I'm reading this really interesting article about the human body.ī: Yeah? Well, we know all about that from biology lessons.Ī: No, we didn't learn much at all at school! They're discovering loads more things all the time.
