Black dwarfdom assures our Sun of choreless, cold, compacted death in Chapter 6 Into the Future of Bang! The Complete History of the Universe by Chris Lintott, Brian May and Patrick Moore.

The cosmic microwave background 300,000 years after the Big Bang brightened dark space that now brandishes Earthly fossilized extinctions, lunar craters and supernova-battered Crab Nebula clouds. The clear-lit past charts as comprehensible a course as the conjectured future for our Sun and a more comprehensible course than a conjectured future for Earth. Observational astronomers disappointingly detect Potentially Hazardous Asteroids (PHAs), which deliver such devastation as dinosaur deaths about every 300,000 years, after disparate orbits drive them past Earth.

Extensive magma reservoirs under extreme pressure, such as the Yellowstone supervolcano under Yellowstone National Park in Wyoming, perhaps effectuated past extinctions through planet-encircling, sunlight-excluding debris clouds.

Human-made disasters, which the three co-authors fit under figuring how to finish ourselves, furnish fatally conjectured futures before our Sun fells Earth within five billion years.

Mature life cycles get our Sun from Main Sequence stages through black dwarfdom by generating coreward contractions and greater core pressures, temperatures and hydrogen-depleting nuclear reactions. Solar hyperluminosity perhaps heralds within one billion years polar-huddled survivors of deserts and cropless lands from floods, melting ice caps, rising sea levels, shifted continental plates. The 9.5-billion-year-long life cycle of our Sun involves increased luminosity by 40 percent within three billion years from now and no surface water anywhere on Earth.

Solar journeys from Earth-friendly Main Sequence stages into Earth-unfriendly red giantdom and white and black dwarfdom jeopardize sustained Earthling well-being on solar-system bodies or space stations.

Solar hyperluminosity perhaps kindles 30-million-year-long Martian warm weather, with melted carbon-dioxide and water ice caps, until small size and weak gravitational pull kill its ever-temporary atmosphere.

Titan, largest satellite of gas giant Saturn, lacks Earth-friendly lodgings since low escape velocity and solar hyperluminosity let loose its cold-linked, sluggish gas molecules into space. Weakened solar gravitational pull, over a half-billion-year time period, moves Earth to a 120-million-mile (200-million-kilometer) astronomical distance from our double-sized, doubly luminous, low-mass, strong-winded, surface-cooled Sun. Five billion years from now the hydrogen-depleted solar core, non-reactive without radiation pressure, nets next-level compression heat and nuclear reactions by outer material gravitationally collapsing coreward.

Not even halfway toward black dwarfdom helium nuclear fusion into beryllium and lithium occasions our Sun's obtaining 2,000-plus times fiercer luminosity that obliterates Mercury and Venus.

Age-provoked instability prompt red giants pulsating outer envelopes outward into planetary nebula, such as cycle tire-looking, dim-lit Ring Nebula in Lyra, that persist about 30,000 years.

Ejection processes quit central stars of outer envelopes and queue different-shaped planetary-system nebulae, from symmetrical M57 to planetary system-commonest clouds, hourglass viewed edge-on and ring face-on. Gravitational collapse results in such great density when core fuel runs out that degeneracy pressure repels any two close-ranging particles with identical charge, mass and energy. Degeneracy pressure balanced with, and stopping, gravitational collapse stabilizes our Sun into Earth-sized, super-dense white dwarfdom, from which Earth stays at a 170-million-mile (270-million-kilometer) astronomical distance.

Our Sun transforms into black dwarfdom in more than 10-plus billion years as dead star, perhaps among the first black dwarf stars, for orbiting ghost planets.
