Evolutionary models predict slow changes in the nature of stars. Now, they say that as stars age, they go through expansions and contractions thought to take millions of years.

But there is evidence that it doesn’t actually take long ages.

Sirius, the brightest star in our nighttime sky, is a blue-white star. It has a dwarf companion that is almost invisible. Now, astronomers from 1,000 years ago said Sirius was red. This suggests that they were actually looking at the companion star and that it has changed significantly in just a few hundred years. This suggests stars don’t take millions of years to age.

Once again, the evidence doesn’t confirm long ages for the universe.
