Story summary

Astrophysicist Dr. Phil Wiseman led a team refuting the South Korean claim that expansion is slowing and dark energy is absent.
The team found the study confused galaxy ages with exploding white dwarf ages, reducing the age gap from five billion to under two billion years.
Applying the galaxy-size correction eliminated the brightness-age link, while Dark Energy Survey data from 1,500 type Ia supernovae showed distance dependence, leaving accelerating-expansion evidence unchanged.
