Some estimates are that there could be one trillion galaxies in the universe (some larger than the Milky Way, some smaller). But if the Milky Way may have dozens of nearly invisible satellite galaxies, that could be true of many other galaxies too...so maybe they need to revise the upward limit for the possible number of galaxies in the universe.
That doesn't change the fact that the earth is the only planet with chocolate, or with the infield fly rule.
