Nonlinear supergravity on a brane without compactification
Abstract:
We show that smooth domain wall spacetimes supported by a scalar field separating two anti-de Sitter-like regions admit a single graviton bound state. Our analysis yields a fully nonlinear supergravity treatment of the Randall-Sundrum model. Our solutions describe a pp-wave propagating in the domain wall background spacetime. If the latter is a Bogomol'nyi-Prasad-Sommerfeld state, our solutions retain some supersymmetry. Nevertheless, the Kaluza-Klein modes generate " pp curvature" singularities in the bulk located where the horizon of the anti-de Sitter region would ordinarily be.

This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...
Schwarzschild Radius and Event Horizon
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape velocity with the...

This has been verified in many experiments. However, space and time are no longer absolute. Two observers moving relative to one another do not agree on the length of objects or the passage of time. The mechanics of objects based on Newton's laws of motion,...
