         Diameter:-

   Diameter of a observable  Universe is

 8.8 x 10^26 m

  
          Mass(ordinary matter):-

   At least 10^53 kg 

 

           Further observational improvement led to the realization that galaxies are uniformly distributed and same in all directions in the universe this mean that Universe has nighter center nor edge.

      At smaller scale, galaxies are distributed in clusters and superclusters which form immanse filament and voids in space,

 Creating a vast foam like structure.
