The prodigious and inconceivable Rapidity assigned by the Ptolemaicks to the Heavens, is by the Copernican Scheme taken off, and a far more easy and tolerable Motion substituted in its room. For is it not a far more easy Motion for the Earth to revolve round its own Axis in 24 hours, than for so great a number of far more massy, and far distant Globes, to revolve round the Earth in the same space of time? If the Maintainers of the Ptolemaick Systeme do object against the Motion of the Earth, that it would make us dizzy and shatter our Globe to pieces, what a precipitant, how terrible a Rapidity must that of the Heavens be? What a Velocity must the Sun have to run its course, at the distance 21 or 22 Semidiameters of the Earth? What a Velocity must that of the Fixt Stars...--From Astro-theology--
Does the Earth spin in the universe or is the Earth fixed and the universe spin around us?
If we were fixed then the star Betelgeuse, which is about 640 light years away, would travel 3.80 X 10^16 km every day at a speed of 1468757.4 times that of light. Since nothing can travel faster than the speed of light (other than a rumor) the planet Earth must rotate.
So, if you think the universe revolves around you, hopefully this demonstration of math and physics will convince you of the error of you ways.

I always thought the Earth revovled around me.
No wait, that was the evil blogger lady who thought that.
Nevermind.
Plus I don't believe in math.
It's a communist plot.
Like the stuff they put in the water.
