Classical mechanics define the tight relationship between motion and energy [1] . Movement is the natural state of everything everywhere, from vibrating atoms to the stars 'fixed in the sky' [2] . On Earth, resting objects rotate with the Earth around its axis, move with Earth around the Sun, with the solar system around the Milky Way’s center, and with our galaxy, apparently accelerated, away from other remote galaxies. There is no absolute rest anywhere.
Stars and galaxies are, of course, not fixed. They move at considerable speeds, but the huge distances involved make the movements imperceptible.
