Mostly Harmless !

Our 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!
