The visible universe is estimated to contain between 1078 and 1080 atoms.

(One estimate at the higher end of the range is 4 x 1079.)

This is the estimated number of atoms in the observableuniverse, but since we do not know the absolute size of the universe, we cannot be certain.

(Most of the matter in the universe is still hydrogen.)
