Witryna6 gru 2024 · Low energy effective action of bosonic string theory possesses a kind of singular static solution which can be interpreted as a naked singularity. Based on the Hohm-Zwiebach action, the naked singularities could be smoothed out by introducing the complete $α^{\\prime}$ corrections of string theory. In this paper, we present two sets … Witryna最后更新 “兰州理论物理中心(筹)”诚聘博士后 (长期有效) 兰州大学量子理论及应用基础教育部重点实验室获批建设
What Would It Be Like to Fall Into a Naked Singularity? [Guest Post]
Witryna14 gru 2024 · 5. The big bang is certainly spacelike. If you use the definition in Penrose 1973, then the big bang is not a naked singularity. See pp. 85-86 of that paper. He defines a naked singularity as one that can be in both the past and future light cones of the same observer.

Gravitational Radiation from a Naked Singularity
Witryna31 sie 2024 · Here the gravitational field suppresses the appearance of “spherical singularities” and only a naked singularity in the very center is possible. The proof uses an assumption that the SF self-interaction ... Toktarbay, S. Motion of test particles in the field of a naked singularity. Phys. Rev. D 2016, 93, 024024. [Google Scholar ... WitrynaThus, both classical and quantum gravity considerations suggest that near extremal charged black holes have arbitrarily large curvature near – even outside – their horizon. This is as bad as a truly naked singularity, because general relativity cannot describe physics in the region of arbitrarily large curvature. Witryna7 lip 2024 · Here we propose a new spherically symmetric naked singularity spacetime which has no photon sphere, and we show that the singularity casts a shadow in the absence of the photon sphere. We discuss some novel features of this shadow and the lightlike geodesics in this spacetime. ... Phys. Rev. D 102, 024022 – Published 7 July … organophosphates vs organochlorines
