Gamma-ray bursts are the most energetic events occurred in the universe. They are usually categorized into long and short gamma-ray bursts according to their durations of being greater than two seconds or not. It is generally believed that the long gamma-ray bursts are produced by the collapse of massive stars to form compact objects such as neutron stars and stellar black holes, while the short gamma-ray bursts are produced by the merger of binary neutron stars. However, the mechanism or mean by which gamma-ray bursts convert their energies into high-frequency radiations remains poorly understood. In this study, a new mechanism for gamma-ray bursts is proposed, in accord with the black hole universe model recently developed by the author from considering a black hole as a spacetime and slightly modifying the big bang theory. According to the black hole universe model, both the merger of stellar black holes to form a larger one and the collapse of a massive star into a stellar black hole would release a huge amount of high-frequency radiation such as gamma-rays. The results obtained for the energy emission by both the long and short gamma-ray bursts can be consistent with measurements. This work is supported by NASA EPSCoR and AAMU title III programs.
