Suppose I have a stick whose length is infinite, then the stick was rotated at one end. Despite playing with a small angular velocity, but should have a linear speed of the other end of the stick (which is at infinite distance) will be very high considering the formula of linear velocity = angular velocity multiplied by the length of the radius. If an infinite radius, it should also be linear velocity at infinite distance is infinite. Could it be the linear velocity at the tip of a rod that is at an infinite distance that would exceed the speed of light? What will happen? Was broken stick? whether the rod was shortened (the stick towards the player)? Or stick it will not be driven at all? (Assume this is done immense room is empty so there is no motion that prevents this staff) There's one more question, I've heard he said during the beginning of the universe formed, there are several dimensions (if not wrong there are 11). However, in its development, only four dimensions namely growing dimensions of length, width, height, and time. While other dimensions continue to shrink. True? Then why are other dimensions to shrink? Is it because we live in four dimensions expanded relatively faster than the other dimension so that the other dimensions seem to shrink? What is the name of the dimensions of it (besides the four dimensions we live in)?
