Nova suddenly stumbled into a realm of nothingness, a world with no concept of time or space. Not even he knew the circumstances of his arrival, yet his appearence was accompanied by a massive, superheated explosion. The extreme temperature gave rise to the passage of time and expansion of space, and the explosion caused the formation and congealment of matter. After hundreds of billions of years, humankind began to call this world "the cosmos".

In general a nova (plural novae or novas) is an exploding star. A nova is a cataclysmic nuclear explosion on a white dwarf, which causes a sudden brightening of the star. A supernova is a stellar explosion that briefly outshines an entire galaxy, radiating as much energy as the Sun is expected to emit over its entire life span, before fading from view over several weeks or months. A luminous red nova (abbr. LRN) is a stellar explosion thought to be caused by the merging of two stars.
