Big Bang Theory or can we drop 'theory' now?

[Prudence]

Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour.
It's orbiting at ninety miles a second, so it's reckoned,
The 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
Through an outer spiral arm at forty thousand miles an hour
Of the galaxy we call the Milky Way.
