We then study the case of gravity for two different boundary conditions, namely spatial infinity and a Brane-World boundary. The new conclusion of this analysis is that the gravitational energy (and linear and angular momentum) is a local expression if our universe is really a boundary of a five-dimensional spacetime.7 pages, 2 figures, talk presented at TMR-conference "Nonperturbative Quantum Effects 2000", ParisHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
