How many universes are in space?

The observable universe contains as many as 200 billion galaxies and, overall, as many as an estimated 1×10²⁴ stars (more stars than all the grains of sand on planet Earth). Typical galaxies range from dwarfs with as few as ten million (10⁷) stars up to giants with one trillion (10¹²) stars.
