Galaxy song

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 nine hundred miles an hour
It's orbiting at nineteen miles a second, so it's reckoned
The sun that is the source of all our power
Now the sun, and you and me, and all the stars that we can see,
Are moving at a million miles a day,
In the outer spiral arm, at fourteen thousand miles an hour
Of a 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 whiz.
As fast as it can go, that's 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 out in space
'Cause there's bugger all down here on Earth!
