Claim CH370:
The creation model predicts galaxies constant and stars unchanging, in the main. They may decay, but they were created entire and did not build up over time.Source:

Response:
- The claim is baseless. The formation of stars takes on the order of
millions of years, so we cannot expect to see major changes as we watch,
but that does not mean the stars are unchanging.
Given our knowledge of physical laws and our observations of stars and interstellar matter, we expect star formation to be occurring continuously, as molecular clouds form and condense. And we see molecular clouds, protostars, and young stars in all stages of formation, in close agreement with what we expect (Pudritz 2002; Ward-Thompson 2002).
The existence of stars with differing amounts of heavy elements is also in good agreement with star formation over time, since the heavy elements come only from supernovae of earlier stars. - Galaxies have changed over time, too. Quasars were more common in the earlier universe; there are no recent ones. We also see galaxies in various stages of colliding.
