Evolutionary models predict very slow changes in the nature of stars. They say that as stars age they go through expansions and contractions in a process that takes millions of years.

But there’s evidence that it doesn’t actually take that long. Sirius, the brightest star in our night sky, is a blue-white star and has a dwarf companion that’s almost invisible. Astronomers from just one thousand years ago said Sirius was red. This suggests they were actually looking at the companion star and it changed significantly in a very short time. It didn’t take millions of years!

Once again, the evidence contradicts evolutionary ideas.
