In order to describe how Alice feels the world around her we can also use the concept of curved spacetime. Logunov school thinks that there is a effective Riemannian space-time in a real visible flat background space-time, they call their theory as Relativistic Theory of Gravitation. Gravity is nothing more than a deformation in the shape of space-time itself. In loop quantum gravity, the four dimensions of spacetime are composed of networks of intersecting loops — ripples of the gravitational field. Flat space-time and negative space-time describe an environment in which the Universe is non-compact, with space extending infinitely, forever in time, in any direction. As I understand, the gravitation of general relativity in effect locally contracts spacetime, counteracting and overcoming any universal expansion of spacetime. It has been suggested that energetic photons propagating in vacuo should experience a non-trivial refractive index due to the foamy structure of space-time induced by quantum-gravitational fluctuations. In order to describe gravity, general relativity uses the concept of curved spacetime. It's the warping in the fabric of space-time due to the mass of an object. The observations are a powerful test of Einstein's theory of general relativity, which says gravity can bend space-time, the fabric that shapes our universe, and the light that travels through it. It is a way to rewrite an old problem. What does this have to do with quantum gravity?
