👉 In physics, a "hemispherically" describes an object that is located at the intersection of two different physical dimensions. This means it has both positive and negative space coordinates, which are represented by its z-coordinate in 3D space. For example, if you have a point (x, y, z) that lies on one side of a line (which can be thought of as being "on the hemispherically"), then this point will have a z-coordinate of either -
