Whenever life gets you down, Ms. Brown And things are hard and tough And people are stupid, obnoxious and daft And you feel that you've had quite enough, enough: Just remember that you're standing on a planet That's evolving and revolving at 900 miles an hour It's orbiting at 90 miles a second, so it's reckoned Round the sun that is the source for 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 In the galaxy we call the Milky Way Now, the galaxy itself contains a hundred billion stars It's a hundred thousand light years side from 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 and billions In this amazing and expanding universe Now, the universe itself keeps on expanding and expanding In every direction it could wish As fast as it can go, the speed of light, you know 12 million miles a minute, that's the fastest thing there is So, remember when you're feeling very small and insecure How amazingly unlikely was your birth And pray that there's intelligent life somewhere up above Because there isn't any down here on earth So, lighten up, and there are stars in the sky Lighten up, it's a good question why But you don't have the answer and neither do I So, meanwhile, let's just all lighten up And remember that you're standing on a planet That's evolving and revolving at 900 miles an hour It's orbiting at 90 miles a second, so it's reckoned Round the sun that is the source for all our power The sun and you and me, 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 In the galaxy we call the Milky Way
