Have a specially made uspez is a cunt coat <| sep |> Being a developer stems from a passion for video games . These guys can go off an make more money with better work conditions elsewhere . Let ' s show some appreciation , just a smidge ? <| sep |> What ' s your problem mate <| sep |> You ' ve asked multiple questions , and that can make it difficult to give a concise answer . Most cosmic simulations begin by assuming everything starts as a uniform distribution of mass , and then under the influence of gravity the mass coalesces to form galaxies , and analogously stars , forming clusters . The reason the uniform distribution doesn ' t collapse perfectly symmetrically to form a single galaxy , or star , is because we add an assumption that there must be slight imperfections in the distribution that make some areas clump together . Measuring and understanding basic relations of stars and galaxies is an activate area of research , and some of my colleagues work in simulating miniuniverses to compare shapes and sizes of simulated galaxies . paper is a bit older 2014 , but essentially says we haven ' t had time yet to investigate how galaxies in close proximity effect each other ' s star formation . binnphdataquery ? bibcode 2014 ApJ . 796 . 51 D d b k eyASTlinktypeABSTRACThigh 5836 b 81 ba 807497
