"Unveiling a Revolutionary Phenomenon: White Dwarf Stars Defy Aging and Alter Star Life Theories"
Astrophysicists have discovered a new phenomenon challenging the traditional understanding of white dwarf stars, which were thought to cool down continuously over time. Some white dwarfs have been found to stop cooling for over eight billion years, and new research has unveiled the mechanism behind this unexpected observation. It appears that in some white dwarfs, the solid crystals formed upon freezing are less dense than the liquid, causing them to float upward and release gravitational energy, interrupting the cooling process. This discovery not only requires revisions to astronomy textbooks but also calls for a reevaluation of the process used to determine the age of stellar populations, as some white dwarfs may be billions of years older than previously thought.
