The gapless fermionic excitations in superfluid He-3-A have the ''rela
tivistic'' spectrum close to the gap nodes. This allowed us to model t
he modern cosmological scenaria of baryogenesis and magnetogenesis. Th
e same massless fermions induce another low-energy property of the qua
ntum vacuum - the gravitation. The effective metric of the space, in w
hich the free quasiparticles move along geodesics, is not generally fl
at. Different order parameter textures correspond to curved effective
space and produce many different exotic metrics, which are theoretical
ly discussed in quantum gravity and cosmology. This includes the conde
nsed matter analog of the black hole and event horizon, which can be r
ealized in the moving soliton. This will allow us to simulate and thus
experimentally investigate such quantum phenomena as the Hawking radi
ation from the horizon, the Bekenstein entropy of the black hole, and
the structure of the quantum vacuum behind the horizon. One can also s
imulate the conical singularities produced by cosmic strings and monop
oles; inflation; temperature dependence of the cosmological and Newton
constants, etc.
