But human scientists believed that no celestial body known as a Black Dwarf Star existed in the universe.
Because the universe's entire 13.7-billion-year lifespan was not enough to nurture one into being.
It should have existed only in theory.
Whether black holes, Neutron Stars, or White Dwarf Stars.
Before they formed, their predecessor stars either underwent a massive explosion or a massive collapse.
This caused their structural forms to change abruptly.
They died in a very short time, becoming corpses.
But the fourth kind of "corpse," the Black Dwarf Star, was different.
It did not possess enough energy to hold a magnificent "funeral" for itself.
It was like a piece of charcoal, slowly burning out over time.
From glowing and radiating heat, it became dim and lifeless, then gradually cooled and turned cold, with most of its body becoming ash.
Its death was like withering—lonely and slow, attracting no attention at all.
This required an extremely long process.
It could take 20 billion years.
Therefore, in a universe only 13.7 billion years old, the legendary Black Dwarf Star should not have appeared.
Yet.
Three billion years ago, a Black Dwarf Star had appeared in the Kepler-16b starfield before them, defying all reason.
It had formed from the three small stars in the Kepler-16b starfield.
It seemed to have ended its own life early through its own power.
The Black Dwarf Star it formed was very likely the first—and the only—Black Dwarf Star in the universe.
It continued to wither and evaporate, becoming a tiny core that drifted between two stars.
Yet wondrously, death and rebirth truly kept transforming into one another.
Because of its own gravity, that tiny core began attracting the surrounding gas clouds and interstellar dust again. After a long 2.8 billion years.
It actually gathered itself back
