Phys. Rev. D 64, 084006 (2001) [20 pages]Oscillatory approach to the singularity in vacuum spacetimes with T2 isometrySee Also: Erratum Received 16 April 2001; published 11 September 2001 We use qualitative arguments combined with numerical simulations to argue that, in the approach to the singularity in a vacuum solution of Einstein’s equations with T2 isometry, the evolution at a generic point in space is an endless succession of Kasner epochs, punctuated by bounces in which either a curvature term or a twist term becomes important in the evolution equations for a brief time. Both curvature bounces and twist bounces may be understood within the context of local mixmaster dynamics although the latter have never been seen before in spatially inhomogeneous cosmological spacetimes. © 2001 The American Physical Society URL:
