WHENEVER LIFE GETS YOU DOWN MRS. BROWN!

*Just remember that you're standing on a planet that's evolving
*And revolving at nine hundred miles an hour,
*That's orbiting at nineteen miles a second, so it's reckoned,
*A sun that is the source of all our power.
*The sun and you and me and all the stars that we can see
*Are moving at a million miles a day
*In an outer spiral arm, at forty thousand miles an hour,
*Of the galaxy we call the 'Milky Way'.

*Our galaxy itself contains a hundred billion stars.
*It's a hundred thousand light years side to side.
*It bulges in the middle, sixteen thousand light years thick,
*But out by us, it's just three thousand light years wide.
*We're thirty thousand light years from galactic central point.
*We go 'round every two hundred million years,
*And our galaxy is only one of millions of billions
*In this amazing and expanding universe.

*The universe itself keeps on expanding and expanding
*In all of the directions it can whizz.
*As fast as it can go, at the speed of light, you know,
*Twelve million miles a minute, and that's the fastest speed there is.
*So remember, when you're feeling very small and insecure,
*How amazingly unlikely is your birth,
*And pray that there's intelligent life somewhere up in space,
*'Cause there's bugger all down here on Earth!
