Does the earth move?
In the days of Aristotle it was believed that the
earth remains at rest and the sun moves round it.
Copernicus initiated the idea that the sun is at
rest and the earth moves round it. Galileo was a
firm believer of this theory and worked hard to
let others know about it. He was warned by the
Church not to spread this idea. As Galileo kept
on doing so, his book Dialogues of Galileo Galilei
was banned and Galileo was sent to prison. On
22 June 1633, Galileo apologized to the Church
and swore not to teach that the earth moves. It is
said that after the apology he muttered: "Eppur si
muove" (indeed it moves).
How fast can one move?
It is interesting to know that no material object
can move at a speed of more than 3 x 108 m/s.

To the best of his knowledge they had already given witness -- that the Earth did not move and that the “annual motion” resided in the Sun. 12 Galileo, Dialogue (ref.
