چکیده
We attempt to study three significant tests of general relativity in higher dimensions, both commutative and non-commutative spaces. In the context geometry, we will consider a solution Einstein’s equation with source given by static, spherically symmetric Gaussian distribution mass. The resulting metric would describe regular or curvature singularity free black hole dimensions. should smoothly interpolate between Schwarzschild geometry at large distance, de-Sitter spacetime short distance. gravitational redshift, lensing, time delay each sector. It be shown that, compared four-dimensional spacetime, there can modifications due presence extra dimensions corrected holes. Finally, shall obtain lower bound on size mass needed form different

Gravitational instability in higher dimensions
We explore a classical instability of spacetimes of dimension D > 4. Firstly, we consider static solutions: generalised black holes and brane world metrics. The dangerous mode is a tensor mode on an Einstein base manifold of dimension D−2. A criterion for instability is found for the generalised Schwarzschild, AdSSchwarzschild and topological black hole spacetimes in terms of the Lichnerowicz s...

متن کاملGravitational coupling constant in higher dimensions
Assuming the equivalence of FRW-cosmological models and their Newtonian counterparts, we propose using the Gauss law in arbitrary dimension a general relation between the Newtonian gravitational constant G and the gravitational coupling constant κ.
متن کاملGravitational Field of A Radiating Star in Higher Dimensions
We obtain fields of a relativistic radiating star of non-static mass in the framework of higher dimensional spacetime. Assuming energy-momentum tensor in Higher dimensions analogous to that considered by Vaidya in 4 dimensions we obtain solution of a radiating spherically symmetric star. The solution obtained here is new in higher dimensions which however reduces to that obtained by Vaidya in 4...
متن کاملGravitational scaling dimensions
A model for quantized gravitation based on simplicial lattice discretization is studied in detail using a comprehensive finite size scaling analysis combined with renormalization group methods. The results are consistent with a value for the universal critical exponent for gravitation, n51/3, and suggest a simple relationship between Newton’s constant, the gravitational correlation length and t...
