Nonsingular Cosmology from an Unstable Higgs Field
  The observed value of the Higgs mass indicates an instability of the Higgs
scalar at large energy scales, and hence also at large field values. In the
context of early universe cosmology, this is often considered to lead to
problems. Here we point out that we can use the instability of the Higgs field
to generate an Ekpyrotic phase of contraction. In the context of string theory
it is possible that at very high energy densities extra states become massless,
leading to an S-brane which leads to the transition between a contracting phase
in the past and the current expanding phase. Thus, the Higgs field can be used
to generate a non-singular bouncing cosmology in which the anisotropy problem
of usual bouncing scenarios is mitigated.
