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 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.
