The term 'ends of the world' can refer to two different things: the North and South Poles. The North Pole is located in the Arctic Ocean, while the South Pole is located in Antarctica. Both poles are the northernmost and southernmost points on Earth, respectively. They are also the points at which the Earth's axis of rotation meets its surface. The North and South Poles are often referred to as the 'ends of the world' because they are the farthest points from the equator.
