An Alternative to Compactification
Abstract
Conventional wisdom states that Newton's force law implies only four noncompact dimensions. We demonstrate that this is not necessarily true in the presence of a nonfactorizable background geometry. The specific example we study is a single 3brane embedded in five dimensions. We show that even without a gap in the KaluzaKlein spectrum, fourdimensional Newtonian and general relativistic gravity is reproduced to more than adequate precision.
