* White dwarfs are the remnants of stars like our Sun. They form after a star like our Sun runs out of fuel and sheds its outer layers, leaving behind a dense, hot core.
* Our Sun is currently in its main sequence phase. This means it's fusing hydrogen into helium in its core, and it has billions of years left before becoming a white dwarf.
* Therefore, a white dwarf must have existed as a star before our Sun even formed. In that sense, the material that makes up a white dwarf is "older" than our Sun, but the white dwarf itself formed after the Sun's birth.
To summarize:
* The Sun is younger than the star that became a white dwarf.
* However, the white dwarf is a product of a star that existed before the Sun, making its material older.
It's a matter of perspective on the term "older"!
