Just remember that you’re standing on a planet that’s evolving and revolving at nine hundred miles an hour, that’s orbiting at nineteen 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 arm, at forty thousand miles an hour, of the galaxy we call the Milky Way.

Our galaxy itself contains a hundred billion stars. It’s a hundred thousand lights years side to side. It bulges in the middle sixteen thousand lights years thick but out by us it’s just three thousand lights years wide. We’re thirty thousand lights years from galactic central point, we go around every two hundred 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 whiz. As fast as it can go, at the speed of light, you know, twelve million miles a minute and that’s the fastest speed thereis. 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 because there’s bugger all down here on earth.
