= Positive energy theorem
{wiki=Positive_energy_theorem}
The Positive Energy Theorem is a significant result in the field of general relativity, primarily related to the properties of spacetime and gravitational fields. It states that, under certain conditions, the total energy (or total mass) of an asymptotically flat spacetime, which describes isolated physical systems, is non-negative. In more technical terms, the theorem asserts that the energy associated with a spacetime configuration cannot be negative, which has implications for the stability of gravitational systems.
