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

Added: 2026-05-22

[00:00:00]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, there's a tiny nucleus, and around it electrons orbit at a massive distance relative [music] to their size.

[00:00:10]If the nucleus were the size of a football, the nearest electron would be about 10 km away. And that's not unique to you. That's every atom in every object in the entire universe, [music] almost completely empty space. So, when you strip all that emptiness away and compress just the actual matter from all 8 billion humans on Earth, the result is smaller than a sugar cube.
