引力在史瓦西半径附近的性质
Properties of gravity near the Schwarzschild radius
摘要：
宇宙的可观测区域的半径是史瓦西半径的数量级。由于球对称性，这允许通过比较理论和观测到的高红移的哈勃图来检查史瓦西半径附近的引力特性。这可以在一个简单的模型中完成，该模型与引力的射影不变方程相联系.本文表明，直到$z=8$的哈勃图证明了在史瓦西半径附近和内部引力的特殊性质.
英文摘要：
The radius of the observable region of the Universe is of the order of its Schwarzschild radius. Due to the spherical symmetry, this allows to check the properties of the gravitational force in the vicinity of the Schwarzschild radius by comparing the theoretical and observed Hubble diagram at high redshifts. This can be done in a simple model that fellows from projective-invariant equations of gravitation.This paper shows that the Hubble diagram up to $z=8$ testifies in favor of the specific properties of gravity near and inside of the Schwarzschild radius.
