In the astrophysics seminar today Tristan Smith (Swarthmore) convinced us, perhaps incidentally to his main point, that the Hubble Constant controversy could be resolved if the baryon acoustic feature (or peaks in the CMB) is moved relative to the vanilla CDM prediction. And it doesn't have to be moved far! So maybe there is just a bit of initial-conditions manipulation to make that happen, and then everything is in agreement! Interesting take on things.
My only other significant research for the day was a discussion with Kate Storey-Fisher (NYU) about the outline of our paper about correlation-function estimation, and a chat with Boris Leistedt (NYU) about a possible pedagogical piece on hierarchical modeling and graphical models.
