Each domain grows radially until the domains touch, at which time, the growth in that direction stops. In the center of the domain there is a nucleus, and along the edge is a wall. Inside the domain are many smaller faults where, due to the increase in linear size of the front, one row of molecules had to split into two. The new inflation scenario differs from recrystallization because growth does not stop when domains contact as spacetime is being created within each domain. Therefore, no distance exists at any time between domains, and characteristics of the domains are governed by quantum, not classical mechanics.
Adjacent domains remain in quantum contact.
The interactions mark their surroundings by disturbing spacetime directly. These disturbances are not sharp faults, but rather energy density disturbances in a quantum like distribution. Energy density disturbances may be read as locally bent spacetime. I believe that these structures are not cosmic strings, but when perturbed by chaos and gravity, may account for much of the structure observed today. Also there would be that monopole kickin' around somewhere.
