In plane geometry, the shortest distance between two points is a line. In spherical geometry, the shortest distance between two points is a segment of a great circle. The distance between one point and another is known as the displacement.

Infinity Incorrect ! The longest distance between those two points is a straight line from one point , running all the way around the world to the second point. Thus the shortest distance together with the longest distance is a full circle around the world with both points on the circle.
From September 21 until March 21, the shortest shadow points north from the equator. From March 21 until September 21, the shortest shadow points south from the equator.
When you curve the line you are travelling you are no longer going directly from one point to the other. If you want to go from one point to another you would want to go directly to the second point.
