A model is presented for the origin of the large scale structure of the universe and their Mass-Radius scaling law ; a fractal power law , M \propto R ^ { D } , with dimension D = 2 , most significantly . The physics is conventional , orthodox , but it is used to fashion a highly unorthodox model of the origin of the galaxies , their groups , clusters , super-clusters , and great walls . The scaling law fits the observational results and the model offers new suggestions and predictions . These include a largest , a supreme , cosmic structure , and possible implications for the recently observed pressing cosmological anomalies .
