# The energy and the linear momentum of space-times in general relativity

@article{Schoen1981TheEA, title={The energy and the linear momentum of space-times in general relativity}, author={R. Schoen and S. Yau}, journal={Communications in Mathematical Physics}, year={1981}, volume={79}, pages={47-51} }

We extend our previous proof of the positive mass conjecture to allow a more general asymptotic condition proposed by York. Hence we are able to prove that for an isolated physical system, the energy momentum four vector is a future timelike vector unless the system is trivial. Furthermore, we allow singularities of the type of black holes.
