Phys. Rev. D 77, 104030 (2008) [5 pages]Instability of the time dependent Hořava-Witten modelReceived 3 January 2008; published 27 May 2008 We consider scalar perturbations in the time dependent Hořava-Witten model in order to probe its stability. We show that during the nonsingular epoque the model evolves without instabilities until it encounters the curvature singularity where a big crunch is supposed to occur. We compute the frequencies of the scalar field oscillation during the stable period and show how the oscillations can be used to prove the presence of such a singularity. © 2008 The American Physical Society URL:
