content: I read somewhere that most minds can't comprehend over about 10,000. I may be wrong on the number there, but it's a relatively low number. As in, try to imagine what 50,000 ants or 10,000,000 pennies looks like. And those numbers aren't close to what's in store to understand the universe.  From the small (there are about 7,000,000,000,000,000,000,000,000,000 atoms in the human body) to the very large (300,000,000,000 stars in the Milky Way), you're not alone in not being able to comprehend them.
