Saturation numérique

Correction :
It seems, then, that the number of atoms in the Universe is at least about 4e78, but perhaps as many as 6e79. I would suggest 1e79 as a reasonable estimate. That is, 10 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 atoms in the total observable universe.
