Aristotle's different statements and some mistakes

  Although Aristotle was the world's famous theorist and philosopher, he still made some statement mistakes around several area. These wrong statements are overturned in the next thousands of years.

  Aristotle said, " force is the cause of the movement of the object". He thought that the object should be moved only by the force of the outside force, the external force ceased, and the motion ceased. It was not questioned for nearly two thousand years from the fourth century B.C. to the 16th century. Now we know that his statement is wrong and the main "culprit" in the practice of Aristotle's misconception is the friction.  The concept of friction was not proposed by Galileo until the 16th century AD.
  Aristotle thought that heavier objects would fall faster than light objects, and this statement was later overturned by Galileo as well.
  Aristotle thought that position and time are the premises of motion. The existence of a position is proved by the fact that the motion includes a bit shift. For example, water evaporates into air and such displacement is a prerequisite for space. The position is the boundary of the object in it. It's interesting that Aristotle realized that although everything in the universe has a position, but the universe as a whole have no position, so we can only assume that the universe is rotating.
  Aristotle's space concept is totally different from Newton's space concept. In Aristotle's opinion, the boundary between the thing and its periphery is integrated. The properties of the object itself determine the geometric properties of the surrounding world. So geometry can't actually be separated from the object. The physical location is determined by the mind. It is a point in the place that surrounds the object, the place where it is measured. the place itself is impossible to exist independently. The way Aristotle constructed his concept of space geometry have similarities with general theory of relativity. His theory rejected Newton;s space model, which was similar to a box and physical movement was happening inside.
