DNews The structure of spiral galaxies is more complex than we thought. Here's how the laws of physics contribute to the shaping of galaxies.Everything We Know About The Andromeda Galaxy - http://bit.ly/2blkOkGSign Up For The Seeker Newsletter Here - http://bit.ly/1UO1PxIRead More:What Process Creates And Maintains The Beautiful Spiral Arms Around Spiral Galaxies? I've Been Told That Density Waves Are Responsible -- So Where Do The Density Waves Come From?http://ift.tt/2bDNRyo""The basic physics of why galaxies have spirals is known, but the details remain controversial, sometimes intensely so. Spirals exist only among flattened or 'disk' galaxies. These galaxies are differentially rotating--that is, the time to complete a full rotation increases with distance from the center. Differential rotation causes any disturbance in the disk to wind up into a spiral form. The trouble with this simple explanation is that the differenti...
