Weapon of mass dissent.

Whenever life gets you down
And things seem sad and bad

Just remember that you're standing on a planet that’s evolving
Revolving at 900 miles an hour.
It’s orbiting at 19 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 orb, at 40,000 miles an hour,
Of the galaxy we call the Milky Way.

Our galaxy itself contains a hundred million stars.
It’s a 100,000 light years side to side
It bulges in the middle 16,000 light years thick,
But out by us it’s just 3,000 light years wide.
We’re 30,000 light years 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.

Our universe itself keeps on expanding and expanding
In all of the directions it can whiz
As fast as it can go, the speed of light you know, 12 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 it's bugger all down here on earth.
