text: Whenever life gets you down, Mrs. Brown,\nAnd things seem hard or tough,\nAnd people are stupid, obnoxious or daft,\nAnd you feel that you've had quite eno-o-o-o-o-ough...\n\nJust remember that you're standing on a planet that's \nevolving\nAnd revolving at nine hundred miles an hour,\nThat's orbiting at nineteen miles a second, so it's \nreckoned,\nA sun that is the source of all our power.\nThe sun and you and me and all the stars that we can see\nAre moving at a million miles a day\nIn an outer spiral arm, at forty thousand miles an hour,\nOf the galaxy we call the "Milky Way".\nOur galaxy itself contains a hundred billion stars.\nIt's a hundred thousand light years side to side.\nIt bulges in the middle, sixteen thousand light years thick,\nBut out by us, it's just three thousand light years wide.\nWe're thirty thousand light years from galactic central \npoint.\nWe go 'round every two hundred million years,\nAnd our galaxy is only one of millions of billions\nIn this amazing and expanding universe.\n\n(calliope interlude)\n\nThe universe itself keeps on expanding and expanding\nIn all of the directions it can whizz\nAs fast as it can go, at the speed of light, you know,\nTwelve million miles a minute, and that's the fastest speed \nthere is.\nSo remember, when you're feeling very small and \ninsecure,\nHow amazingly unlikely is your birth,\nAnd pray that there's intelligent life somewhere up in \nspace,\n'Cause there's bugger all down here on Earth.\n\nSource: \n"The Galaxy Song" \nEric Idle, Monty Python \n\nhttp://www.gecdsb.on.ca/d&g/astro/music/Galaxy_Song.html
