With the development of social networks, the impact of rumor propagation on human lives is more and more significant. Due to the change of propagation mode, traditional rumor propagation models designed for word-of-mouth process may not be suitable for describing the rumor spreading on social networks. To overcome this shortcoming, we carefully analyze the mechanisms of rumor propagation and the topological properties of large-scale social networks, then propose a novel model based on the physical theory. In this model, heat energy calculation formula and Metropolis rule are introduced to formalize this problem and the amount of heat energy is used to measure a rumor鈥檚 impact on a network. Finally, we conduct track experiments to show the evolution of rumor propagation, make comparison experiments to contrast the proposed model with the traditional models, and perform simulation experiments to study the dynamics of rumor spreading. The experiments show that (1)聽the rumor propagation simulated by our model goes through three stages: rapid growth, fluctuant persistence and slow decline; (2)聽individuals could spread a rumor repeatedly, which leads to the rumor鈥檚 resurgence; (3)聽rumor propagation is greatly influenced by a rumor鈥檚 attraction, the initial rumormonger and the sending probability.
