Domain walls ...

"A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. Domain walls are also sometimes called kinks in analogy with closely related kink solution of the sine-Gordon model or models with polynomial potentials.^[1][2][3] Unstable domain walls can also appear if spontaneously broken discrete symmetry is approximate and there is a false vacuum.

A domain (hyper volume) is extended in three spatial dimensions and one time dimension. A domain wall is the boundary between two neighboring domains. Thus a domain wall is extended in two spatial dimensions and one time dimension.

Important examples are:

• Domain wall (magnetism), an interface separating magnetic domains
• Domain wall (optics), for domain walls in optics
• Domain wall (string theory), a theoretical 2-dimensional singularity."

those that bring us - 'I' into being,
and yes, those that [try to] take us apart.
