Exploring the topic of the future of the solar system.

Future of the Sun: Once the Sun stops fusing helium in its core and ejects its layers in a planetary nebula in about 8 billion years, it will become a white dwarf and, over trillions of years, eventually will no longer emit any light becoming a black dwarf. A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently to no longer emit significant heat or light. Because the time required for a white dwarf to reach this state is calculated to be longer than the current age of the universe at the time of this video (13.8 billion years), no black dwarfs are expected to exist in the universe at the present time. Once the sun becomes a black dwarf, the Sun will not be visible to the equivalent of the naked human eye, removing it from optical view even if the gravitational effects are evident. The estimated time for the Sun to cool enough to become a black dwarf is at least 10^15 (1 quadrillion) years, though it could take much longer than this. At the end of a black dwarf's life, the onetime star will experience proton decay and eventually evaporate into an exotic form of hydrogen.
