Interesting Facts About Density:

Osmium is the densest naturally occurring element.
Osmium has a density of about 22,590 kg/m³, making it almost twice as dense as lead. A sugar-cube-sized piece would weigh nearly as much as a large apple!

Black holes have "infinite" density.
In theory, the mass of a black hole is compressed into an infinitely small point - a singularity - where density becomes infinite. That’s one reason black holes are so mysterious.

Humans can intuitively sense density.
Even without calculations, we judge objects’ density when lifting them. That’s why a metal spoon "feels heavier" than a plastic one - even if they’re the same size.
