The sun and you and me, and all the stars we see
Are moving at a million miles a day
In an outer spiral arm, at 40,000 miles an hour,
of the galaxy we call the Milky Way.
Our Galaxy itself contains 100
billion stars
It's 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 and billions
In this amazing and expanding universe.
The universe itself
keeps expanding and expanding
in all directions
it can whizz 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 are feeling
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.
