Sazetak:
Due to the fact that certain aspects of general relativity are generic 
features of curved spacetime, various gravitational phenomena, such as 
apparent and event horizons and Hawking radiation,
can be studied using analog models of gravity. In contrast to general 
relativity, where geometry of a spacetime is determined by the Einstein 
equations, in analog models geometry and evolution of
analog spacetime are determined by the equations of fluid mechanics. In 
particular, we apply the formalism of analog gravity to the expanding hadronic 
fluid. The analog metric tensor depends
locally on the soft pion dispersion relation and the four-velocity of the 
fluid. The analog expanding spacetime takes the form of an FRW universe, with 
the apparent and trapping horizons defined
in the standard way.
