Hydrogen atoms is the most abundant atomic mass structure in the Universe.the bulk mass of stars is basically made of Hydrogen Atoms.
The average mass of a Star is approx in the order of 10 ^30 kilograms..An estimated of the number of Stars in the Universe is in the order of 10^24 Stars in the finite containment volume of the Universe.
Hence all the stars in all the Galaxies are floating inside a granular Singularity particle of space structure having a diameter in the order of 10^-78 meters. The finite containment volume of the Universe is estimated to be in the order of 10^69 Kilometer cube.
