Strong cosmic censorship is the conjecture which asserts that, generically, general relativity is a deterministic theory, in the same sense that classical mechanics is a deterministic theory. After an introduction to the conjecture, I will explain my recent work addressing strong cosmic censorship for T2-symmetric spacetimes with positive cosmological constant. In the case of collisionless matter, I will complete the proof of the conjecture. In the vacuum case, I will prove that the conjecture holds for the special cases where the area of the group orbits does not vanish on the past boundary. Finally, I will discuss another set of results concerning the area of the group orbits for T2-symmetric solutions or hyperbolic symmetric solutions, in the presence of collisionless matter.
