So... imagine yourself standing in the centre of St Pauls Cathedral. If a single atom was the size of St Pauls, then the nucleus - the centre of the atom containing most of its mass - would be about the size of a single grain of sand. All the space around the grain if sand, the entire interior of St Pauls, is essentially full of nothing. Empty. This is the stuff we’re made of remember, so if all the space inside us were removed, the planet’s entire population would apparently reduce down to the size of a apple.
That BLOWS my mind.
