Bright galaxies give way to dark voids in this artist’s impression of the universe’s distant future. The study estimates that white dwarfs could evaporate in about 10⁷⁸ years if a proposed process similar to Hawking radiation occurs.
A new calculation puts white dwarf evaporation at roughly 10^78 years if a proposed form of gravitational particle production occurs.
