People who believe in an old universe also believe Achernar is a couple hundred million years old, according to them, young enough to still be fusing [[hydrogen]] into [[helium]] in its core. They think it will burn through its core fuel quickly however,  and eventually evolve into a large white dwarf, much like [[Sirius#Sirius_B|Sirius B]].<ref>http://stars.astro.illinois.edu/sow/achernar.html</ref>

In the cosmological model of a billions of years old universe Achernar is theorized to be a couple hundred million years old, young enough to still be fusing [[hydrogen]] into [[helium]] in its core. Because of the star's high mass, it will burn through its core fuel quickly however,  and eventually evolve into a large white dwarf, much like [[Sirius#Sirius_B|Sirius B]].<ref>http://stars.astro.illinois.edu/sow/achernar.html</ref>
