The description of the dynamics of the Universe at the Planck era is made through the quantization of a Friedmann-Robertson-Walker (FRW) model with positively curved spatial sections. The material content consists of a positive cosmological constant and a perfect fluid in the form of dust. The results show that the universe can emerge from its initial phase through a quantum tunneling mechanism.
