11. DEAD STARS

Low-mass stars fight gravity to a standstill by becoming white dwarfs — degenerate spheres of ashes left over from nuclear burning. If they gain too much mass, however, these ashes can re-ignite, producing a titanic explosion. High-mass stars may make a last stand as neutron stars — degenerate spheres of neutrons. But at slightly higher masses, gravity triumphs and the result is a black hole — an object with a gravitational field so strong that not even light can escape.
