And when you look at the sky you know you are looking
at stars which are hundreds and thousands of light-
years away from you. And some of the stars don’t even
exist anymore because their light has taken so long to
get to us that they are already dead, or they have
exploded and collapsed into red dwarfs. And that makes
you seem very small, and if you have difficult things in
your life it is nice to think that they are what is called
negligible, which means that they are so small you don’t
have to take them into account when you are
calculating something. (p. 126-127)
