Editing Black dwarf (section)

==Future of the Sun==
Once the [[Sun]] stops fusing helium in its core and ejects its layers in a [[planetary nebula]] in about 8&nbsp;billion years, it will become a [[white dwarf]] and also, over trillions of years, eventually will no longer emit any light. After that, the Sun will not be visible to the equivalent of the [[naked eye|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<sup>15</sup> (1 quadrillion) years, though it could take much longer than this, if [[weakly interacting massive particle]]s (WIMPs) exist, as described above. The described phenomena are considered a promising method of verification for the existence of WIMPs and black dwarfs.<ref>{{Cite journal |last1=Kouvaris |first1=Chris |last2=Tinyakov |first2=Peter |date=2011-04-14 |title=Constraining asymmetric dark matter through observations of compact stars |url=https://link.aps.org/doi/10.1103/PhysRevD.83.083512 |journal=Physical Review D |language=en |volume=83 |issue=8 |pages=083512 |doi=10.1103/PhysRevD.83.083512 |arxiv=1012.2039 |bibcode=2011PhRvD..83h3512K |s2cid=55279522 |issn=1550-7998}}</ref>
