Everything in the Universe changes by adding enough mass

"There are enormous numbers of small bodies, from tiny moonlets to asteroids to comets and more, that simply aren't massive enough to pull themselves into hydrostatic equilibrium."

"Once a star dies, there are a number of possible fates that can ensue as well, as a stellar corpse can remain as a white dwarf, a neutron star, or a black hole."

"Everything else that exists today can be changed by adding enough mass. Here's what informs those dividing lines in our cosmos."

"Those stars were where the very first heavy elements were produced: elements heavier than helium like carbon, nitrogen, oxygen, neon, silicon, sulfur, iron, nickel, and cobalt."

In the Universe, objects range from small bodies like moonlets and asteroids to massive stars and black holes. The mass of an object dictates its classification and properties. Stars can evolve into white dwarfs, neutron stars, or black holes upon death. Adding mass can transform most objects into different classes, except for black holes. The origins of all matter trace back to initial clouds of material that formed stars, which produced heavy elements essential for the creation of normal matter.
