Preferred Frame in Brane World

TL;DR

This paper explores how brane world models revise special relativity by introducing a preferred frame, leading to modified gravitational contraction formulas that resemble Lorentz transformations despite relativity principle violations.

Contribution

It proposes a model where a preferred frame exists in brane worlds, altering the usual relativity principles and deriving modified interval contraction formulas.

Findings

Existence of a preferred frame in brane models.

Modified gravitational contraction formulas similar to Lorentz ones.

Relativity principle is violated on the brane.

Abstract

In the framework of brane models the postulates of special relativity theory is revised. It is assumed that there exists preferred frame and relativity principle is violated on the brane. Because of trapping any moving object on the brane is really accelerated and the formulas for gravitational contraction of the intervals (containing the escape speed) appears to be equivalent to ordinary Lorentz ones.
