Gravitational waves and cosmic boundary

C Shi, X Che, Z Huang, YM Hu, J Mei - arxiv preprint arxiv:2411.17177, 2024 - arxiv.org
Space-based gravitational wave detectors have the capability to detect signals from very
high redshifts. It is interesting to know if such capability can be used to study the global …

Intrinsic Torsion, Extrinsic Torsion, and the Hubble Parameter

B McInnes - arxiv preprint arxiv:2412.08990, 2024 - arxiv.org
We study the intrinsic and extrinsic torsions (defined by analogy with the intrinsic and
extrinsic curvatures) of the spatial sections of torsional spacetimes. We consider two …
