A sun's corpse so dense a teaspoon of it outweighs a mountain.
means The collapsed core left behind when a massive star explodes, packed so tightly that protons and electrons are crushed together into neutrons.
from A straightforward scientific compound: 'neutron' (coined in the early 1930s from 'neutral,' for the newly discovered particle with no electric charge) plus 'star.' The object itself was theorized not long after the neutron's discovery, as physicists wondered what would happen if a dying star collapsed so far that its matter turned entirely to neutrons — the name simply describes the physics, no myth required.
- density
- packs more mass than the sun into a city
- spin rate
- some rotate 700 times per second
- surface gravity
- strong enough to flatten mountains into millimeters
- origin
- leftover core of a star that exploded
