Like sands through the hourglass ...

Here's something to blow your mind: Go outside at night, hold up your hand over a dark patch of the night sky, and make a tiny circle between your thumb and forefinger about the size of a dime. In that dark spot, about 100,000 galaxies, each containing billions of stars, can be seen with a powerful enough telescope. There are more stars in the universe than there are grains of sand on all of the beaches on Earth.
