  It was proposed recently that the black hole may undergo a transition to the
state, where inside the horizon the Fermi surface is formed that reveals an
analogy with the recently discovered type II Weyl semimetals. In this scenario
the low energy effective theory outside of the horizon is the Standard Model,
which describes excitations that reside near a certain point $P^{(0)}$ in
momentum space of the hypothetical unified theory. Inside the horizon the low
energy physics is due to the excitations that reside at the points in momentum
space close to the Fermi surface. We argue that those points may be essentially
distant from $P^{(0)}$ and, therefore, inside the black hole the quantum states
are involved in the low energy dynamics that are not described by the Standard
Model. We analyse the consequences of this observation for the physics of the
black holes and present the model based on the direct analogy with the type II
Weyl semimetals, which illustrates this pattern.
