Query: Topological pseudodefects of a supersymmetric $SO(10)$ model and
  cosmology   Obtaining realistic supersymmetry preserving vacua in the minimal
renormalizable supersymmetric $Spin(10)$ GUT model introduces considerations of
the non-trivial topology of the vacuum manifold. The $D$-parity of low energy
unification schemes gets lifted to a one-parameter subgroup $U(1)_D$ of
$Spin(10)$. Yet, the choice of the fields signaling spontaneous symmetry
breaking leads to disconnected subsets in the vacuum manifold related by the
$D$-parity. The resulting domain walls, existing due to topological reasons but
not stable, are identified as topological pseudodefects. We obtain a class of
one-parameter paths connecting $D$-parity flipped vacua and compute the energy
barrier height along the same. We consider the various patterns of symmetry
breaking which can result in either intermediate scale gauge groups or a
supersymmetric extension of the Standard Model. If the onset of inflation is
subsequent to GUT breaking, as could happen also if inflation is naturally
explained by the same GUT, the existence of such pseudodefects can leave
signatures in the CMB. Specifically, this could have an impact on the scale
invariance of the CMB fluctuations and LSS data at the largest scale.
