Loop quantum gravity effects on forming a black hole and its image

报告摘要： The quantum Oppenheimer-Snyder model is introduced by applying the result of loop quantum cosmology. Since there exists a black hole to while hole transition, the image of the black hole in the universe earlier than ours can be observed by us. Thus the black hole image in our universe will be changed and hence encodes the information of quantum gravity.
