And things seem hard or tough
And people are stupid, obnoxious or daft
And you feel that you've had quite enough...
Just remember that you're standing on a planet that's evolving and revolving at 900 miles an hour
That's orbiting at 90 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
In an outer spiral arm, at 40,000 miles an hour, of a galaxy we call the Milky Way
[Galaxy Song lyrics on http://www.metrolyrics.com]
Our Galaxy itself contains a hundred billion stars, it's a hundred thousand lightyears side to side
It bulges in the middle, 16,000 lightyears thick, but out by us it's just 3,000 lightyears wide
We're 30,000 lightyears from galactic central point, we go round every 200 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, 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.
