Fine-Tuning Stephen Hawking's Theory of Mass

Advanced geometry adds to the understanding of mass in general relativity

Durham, NC - If you want to know your body's mass, you hop on a scale and watch the needle swing. But if you want to know the mass of a region out in space, there's no cosmic equivalent -- the best you can do is consult a geometric formula.

Three recent mathematical proofs take aim at refining one of the most useful of these formulas: Stephen Hawking's definition of a region's mass in a spacetime. A team of three mathematicians and physicists recently published their work on the pre-print website arXiv.org.

(Time flat refers to the surface staying in the present, as opposed to part of the surface being in the future and part being in the past.)

An interesting concept. Thanks, Waspie.
