I learned something the other day that has been bothering me ever since. I read that if our Solar System were the size of a quarter, the Sun and orbiting planets would be no more than microscopic specks of dust with orbits represented by the flat disc of the coin. On this scale, the diameter of our Milky Way galaxy holding us is roughly the size of the United States.
Given
that we are surrounded by billions of distant galaxies, how insignificant does
that make us?
