There exists a variety of exact solutions of the scalar field Einstein equations, allowing for “phantom regions” with negative kinetic field term. These regions can be cut out, their boundaries being sewn together in such a way that neither the scale factor (along with its first two derivatives) nor density or pressure will experience a jump. Such a domain surgery eliminates the “Big Rip” scenario, substituting for it the standard inflation.
