In this spacetime, it is possible to come up with coordinate systems such that if you pick a hypersurface of constant time ( a set of points that all have the same time coordinate, such that every point on the surface has a space-like separation, giving what is called a ' space-like surface ') and draw an " embedding diagram " depicting the curvature of space at that time, the embedding diagram will look like a tube connecting the two exterior regions, known as an " Einstein – Rosen bridge ".
