Evolutionists now admit that galaxies cannot evolve from one type to another.a There are also good reasons that natural processes cannot form galaxies.b Furthermore, if spiral galaxies were billions of years old, their arms or bars would be severely twisted.c [See Figure 230 on page 455.] Because they have maintained their shape, either galaxies are young, or unknown physical phenomena are occurring within galaxies.d Even structures composed of galaxies are now known to be so amazingly large and so elongated that they could not have formed by slow gravitational attraction.e Slow, natural processes cannot form such huge galactic structures; rapid, supernatural processes may have.
