The Galaxy Song

	  		G    G7  
Just re-  
C  
member that you're standing on a planet that's evolving  
C                                  G   
revolving at nine-hundred miles an hour  
G7  
and orbiting at nineteen miles a second, so it's reckoned,  
                                    C  
a sun that is the source of all our power.  
C  
Now the sun and you and me, and all the stars that we can see  
A7                           F  
Are moving at a million miles a day  
F7                               C  
In an outer spiral arm at forty thousand miles an hour   
G7                              C  
of the galaxy we call the Milky Way.  
  
  
Our galaxy itself contains a hundred million stars,  
it's a hundred thousand light-years side to side,  
it bulges in the middle, sixty thousand light-years thick,  
but out by us it's just three thousand light-years wide.  
We're thiry thousand light-years from galactic central point  
We go 'round every two hundred million years,  
and our galaxy itself is one of millions of billions in this  
Amazing and Expanding Universe!  
  
Break   
  
  
The 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, y'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.
