If the universe is billions of years old the older galaxies should not be spiral; they would have lost their shape by now.
But the ‘older’ galaxies have retained their shape. Spiral arms are clear indications of youth, yet many evolutionary scientists claim they are old. If old the tips of the spirals, moving slower, would blend into the rest of the faster spinning inner components creating a circular blob. Astronomers would not be able to see a spiral design.
The Bible says eleven times that ‘God stretched out the heavens…” He created the galaxies as they are, young. He created them with their variety of beautiful designs, including spirals.
