A teaspoon of neutron star material would weigh 10 million tons
A neutron star is the collapsed core of a massive star after a supernova — so dense that protons and electrons are forced together into neutrons. A neutron star typically has the mass of 1.4–2 Suns compressed into a sphere about 20km across (roughly the size of a city). The resulting density means a single teaspoon of neutron star material would weigh about 10 million metric tons — more than the entire human population combined. The gravity at the surface is 200 billion times Earth's gravity.
Density is abstract until you apply it to a teaspoon. The collision of the domestic (a teaspoon in your kitchen) with the cosmic (material that outweighs all of humanity) makes the universe's extremes feel tangible.
