Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour.
That's orbiting at ninety 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.

The 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 of billions
In this amazing and expanding universe.

[interlude]

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.
