The late 19th Century is the age of change physics, Einstein from the experimental facts and on the new test of the basic concepts of physics, in theory, made a fundamental breakthrough. Some of his achievements greatly pushed forward the development of astronomy. His quantum theory of astrophysics, in particular theoretical astrophysics have greatly affected. Theoretical Astrophysics of a mature aspects - star atmospheric theory is that in quantum theory and the theory of radiation on the basis built. Einstein's special theory of relativity successfully revealed the energy and quality of the relationship between the settlement of the long-standing sources of stellar energy problems. In recent years an increasing number of high-energy physics discovered phenomenon, the special theory of relativity to explain this phenomenon has become a basic theoretical tools. His general theory of relativity also solve a mystery for many years on astronomy, and inferred was later verified the light bending phenomenon, many also became the theoretical basis astronomical concepts.
