Also, Lisi notes the use of explicit symmetry breaking in building his action, rather than offering a more desirable spontaneous symmetry breaking mechanism.

Different bubbles may experience different spontaneous symmetry breaking resulting in different properties such as different physical constants.

This is the mechanism by which spontaneous symmetry breaking gives mass to fermions.

Can spontaneous symmetry breaking be predicted, or is this example an oversimplification?

In field theory, there are two possible ways to implement the breaking of a symmetry: explicit and spontaneous.

This is not the case for spontaneous symmetry breaking due to fermion condensation, though.

For spontaneous symmetry breaking to occur, there must be a system in which there are several equally likely outcomes.

If the boundary is a gapped degenerate state, the degeneracy may be caused by spontaneous symmetry breaking and/or (intrinsic) topological order.

This field undergoes spontaneous symmetry breaking due to the shape of its interaction potential.
