Abstract. The questions regarding the quantum origin of the universe, the black hole information problem, and the cosmological constant problem, can all be argued to involve infrared issues of quantum gravity. In order to make progress towards a solution of these problems, it may therefore make sense to first explore their possible infrared connections. In this proceeding, I will summarise some recent progress we have made in exploring infrared issues in de Sitter analogous to issues with black hole evaporation. In particular, I will here focus on recent work on asymptotic symmetries and patient observers. Patient observers are essentially observers with (gravitational) memory.
