It is found that if theĮnergy-momentum tensor falls off at a rate faster than $\sim t^$. It was later developed somewhat more in the short story Vacuum Diagrams. Structure, which was not clear in the previous works. It was first briefly described in the conclusion of Timelike Infinity when it was encountered by Michael Poole who had been pushed several million years into the future. Theĭefinition gives a systematized picture of hierarchy in the asymptotic Of the asymptotic flatness is naturally introduced from the rate. Then there were bad times: Earth was occupied by the faceless, brutal Qax. The second novel in Stephen Baxters Xeelee sequence.First there were good times: humankind reached glorious heights, even immortality. Understand physically what spacetimes are investigated. Timelike Infinity: the strange region at the end of time where the Xeelee, owners of the universe, are waiting. Asymptotic flatness is characterized by the fall-off rate of theĮnergy-momentum tensor at timelike infinity, which makes it easier to Necessary in the previous works on asymptotically flat spacetimes at timelike Introduction of the troublesome differentiability conditions which were Provides unit spacelike 3-hyperboloid timelike infinity and avoids the Infinity for an isolated system with a source is proposed. Timelike direction, a new definition of asymptotic flatness at timelike Download a PDF of the paper titled Timelike Infinity and Asymptotic Symmetry, by Uchida Gen and Tetsuya Shiromizu Download PDF Abstract: By extending Ashtekar and Romano's definition of spacelike infinity to the
