You say No one has ever posited a theory for galaxy creation by merging objects but that is no longer true. Recent observations with the DEEP2 Redshift Survey and the Hubble Space Telescope show that spiral galaxies as well as elliptical galaxies form from mergers.[1] See Galaxy formation and evolution. A lovely video illustrates how this happens and show that the mergers at times may look like fission.[2] StarryGrandma (talk) 21:15, 19 July 2016 (UTC) References
