Whenever life gets you down, Mrs. Brown,
And things seem hard or tough,
And people are stupid, obnoxious or daft,
And you feel that you've had quite eno-o-o-o-o-ough...

Just remember that you're standing on a planet that's evolving,
And revolving at 900 miles an hour,
That's orbiting at 19 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 40,000 miles an hour
Of the Galaxy we call the Milky Way.

Our Galaxy itself contains 100 billion stars
It's 100,000 light years side to side
It bulges in the middle, 16,000 light years thick
But out by us it's just 3,000 light years wide

We're 30,000 light years from galactic central point,
We go round every 200 million years
And our Galaxy is only one of millions and billions
In this amazing and expanding Universe
As fast as it can go, at the speed of light you know,
12 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 it is your birth
And pray that there's intelligent life somewhere up in space,
Because there's bugger all down here on Earth.
