The Nature of Quantum Gravity

Kazuharu Misawa, Jun-ichi Matsumoto, Takuya Hase, Atsushi Matsumoto

Comments: 39 pages

In this paper, we study the quantum gravity theory of single layer BMS model. We show that its quantum gravity action is zero on the surface of the BMS model. This result shows that quantum gravity theory is not a generalization of Einstein gravity.

The Impact of a Black Hole on the Temperature and Theories of Gravity

Jun-ichi Matsumoto, Takuya Hase, Atsushi Matsumoto

Comments: 55 pages

We study the temperature and the gravitational waves of a Schwarzschild black hole in the context of the predictions of the black hole thermodynamics. We find that the gravitational waves induced by the black hole can be used to measure the temperature and the temperature gradient of the black hole. Our results represent an improvement of the observational method of black hole thermodynamics. We also predict that the black hole can significantly affect the universe, including the cosmological temperature.
