Huh? You couldn't count that "in nature"  it's bigger than the number of particles in the galaxy (IIRC). It's just an incredibly large number. It's countable in the mathematical sense, but not in practice  it'd take longer than the age of the universe. Even if you could count to it, you could easily count to a googleplex +1, which is bigger.
