There is no real world flat surface which goes on forever. It is a geometric idealised concept. So, since there is not even a first such thing, there cannot be another.

The flat surface that goes on and on in all directions has no boundaries. This flat surface is called infinite surface. Accordingly, the answer is that the flat surface that goes on and on in all directions is called an infinite surface.

An endless flat surface, also known as an infinite plane, is a theoretical concept in geometry that extends indefinitely in all directions. It has the properties of being flat, meaning that at any point on the plane, the surface is perfectly level with no curvature. In mathematics, an infinite plane is often used as a simplified model for understanding concepts such as coordinate systems, vectors, and geometric shapes.
