Whenever life gets you down, Mrs. Brown, and things seem hard, or tough
When people are stupid, obnoxious or daft, and you feel that you've had quite enough...

Just remember that you're standing on a planet that's evolving
And revolving at 900 miles an hour
It's orbiting at 19 miles a second, so it's reckoned
The 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 400,000 miles an hour
In the Galaxy we call the Milky Way

Our Galaxy itself contains 500 billion stars
It's 100,000 light-years side-to-side
It bulges in the middle, 6 000 light-years thick
But out by us it's just a thousand 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 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
Pray that there's intelligent life somewhere up in space
Because there's bugger all down here on Earth
