White dwarfs may re-ignite and explode as supernovas if they get more material. For a hypothetical proton lifetime of 1037 years, Adams and Laughlin calculate that proton decay will raise the effective surface temperature of an old one-solar-mass white dwarf to approximately 0.06 K. Although cold, this is thought to be hotter than the cosmic background radiation temperature 1037 years in the future. Re-ignition.

These will occur if pycnonuclear (density-based) fusion processes much of the star to iron, which would lower the Chandrasekhar limit for some black dwarfs below their actual mass. [10]:§IVB, It is speculated that some massive black dwarfs may eventually produce supernova explosions. Consequently, brown dwarfs are considered a missing link between gas giant planets and small stars, with those objects below the lower limit defined as sub-brown dwarfs, and those above the upper limit including the least massive red dwarf stars. Even the universe. She’s worked in the digital media industry for over a decade. The closer you get to a black hole, the slower time runs. A black dwarf is a white dwarf that has cooled down to the temperature of the cosmic microwave background, and so is invisible.
