The Mind-Boggling Emptiness Within Even the Hardest Things!

Alright, so you know how a diamond is one of the hardest, most unyielding materials on Earth, right? You can’t crush it with your bare hands, it feels incredibly solid, dense, and, well, there.

But here’s a little secret that’ll make you look at everything around you—and even yourself—a bit differently: even that super-solid diamond is almost entirely empty space!

I know, right? It sounds wild. When you hold a sparkling diamond in your hand, you’re experiencing something that’s roughly 99.9999999% empty space. Think about that for a second! It’s not just diamonds, either; it’s everything made of matter: your desk, your cup of coffee, the air you breathe, and yes, you!

The Ever-Changing You: Why You're Practically a Brand New Person Every Decade!

Did you know that, in a really cool and mind-bending way, you’re not actually made of the exact same stuff you were made of a decade ago? It’s true! While you might feel like the same person, most of the atoms that make up your body are actually replaced every 7 to 10 years.

Think about it like this: your body is an incredible, self-repairing, self-rebuilding machine. Your skin cells are constantly flaking off and being replaced with fresh ones, a process that takes only a few weeks. Your stomach lining? It’s rebuilt every few days! Even your bones, which seem so solid and permanent, are undergoing a slow but constant remodeling, with old bone tissue being broken down and new tissue being laid down. This entire skeletal turnover can take about 10 years for a complete refresh. And your liver cells get a complete overhaul every year or so.

Hey there! Ever stop to think about something as fundamental as… a single second? Like, what is it, really? For most of history, and even today in our everyday thinking, we’d probably say, ‘Oh, it’s just one sixtieth of a minute, which is one sixtieth of an hour, which is one twenty-fourth of a day!’ And you’d be right, in a general sense. That’s how we’ve always conceptually broken down time based on the Earth spinning on its axis. Pretty straightforward, right?
