While the celebrated Penrose-Hawking singularity theorems show that 'singularities' are a robust prediction of Einstein's general relativity, the theorems say little about the quantitative behaviour of near-singularity spacetimes. This was subsequently explored in physics heuristics of Belinski-Khalatnikov-Lifshitz, who suggest a chaotic and oscillatory approach to singularity punctuated by so-called 'BKL bounces'. In this talk, we present recent works justifying these bounces in symmetric, but inhomogeneous spacetimes; one crucial ingredient is proving the asymptotically velocity term dominated (AVTD) assumption of BKL.
