Rather than a smooth spiral with star systems emanating from a scattered core, the inner galaxies that started the universe appear to attract objects in a different way, with the stars gathering up an abundance of gas and dust and being pulled towards them. a denser center, which causes a faster rotation, similar to a swinger swinging his arms for a faster spin. Stars that acquire material by picking up dust and debris in this way grow faster than any other we are familiar with, doubling in size every ten million years compared to the slower growth rate of our home galaxy, the Milky Way, which doubles in size. every 10 billion years.
