Resumo: In this talk, I introduce models describing generic spatial singularities (e.g., the Big Bang) in modified gravity theories. These perturb Bianchi models from general relativity (GR) via a parameter v ∈ (0, 1), recovering GR at v = 1/2. I overview the invariant sets (Bianchi types) and their dynamics, focusing on the type IX attractor for v ∈ (1/2, 1), proved in [1]. This establishes an analogue of Ringstrom’s attractor theorem in GR [3, 4] for supercritical theories.
