Whenever life gets you down, Mrs. Brown,
And people are stupid, wicked, or daft,
And you feel that you've had quite enouuuuuuuuuuuugh . . .
Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour.
It's orbiting at ninety 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
Through 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 lightyears side to side.
It bulges in the middle, sixteen thousand lightyears thick,
But out by us it's just three thousand lightyears wide.
We're thirty thousand lightyears from galactic central point,
We go round every two hundred million years.
And our galaxy is only one of millions and 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!
