All 8 Billion Humans Would Fit Inside a Sugar Cube — Here's Why

Did you know that if you removed all the empty space from every atom in every human on Earth, we'd all fit inside a sugar cube? Every atom in your body is almost entirely empty space. At the center is a tiny nucleus — and around it, electrons orbit at a massive distance relative to their size. If the nucleus were the size of a football, the nearest electron would be about 10 kilometers away. And that's not unique to you. That's every atom, in every object, in the entire universe. The chair you're sitting on, the phone in your hand — almost completely empty space. Strip away all that emptiness and compress just the actual matter from all 8 billion humans on Earth — and the result is smaller than a sugar cube.
