Today we have quite stringent constraints on possible violations of the Weak Equivalence Principle from comparison acceleration test-bodies different composition in Earth's gravitational field. In present paper, propose a test strong field black holes. We construct relativistic reflection model which either massive particles gas accretion disk or photons emitted by may not follow geodesics spac...

It is well known that Newton’s work on mechanics depended in a crucial way the previous observations of Galileo. The key insight Galileo was one can analyze motion bodies using experiments and mathematical equations. One experimental observation roughly emerges from this modern terms two objects different mass are simultaneously released rest allowed to fall under influence gravity through vacu...
