Astronomy, Cosmology, & Physics round up, November 2019: Hubble Constant mystery, Moments before the Big Bang, Universe connected by giant structures, Dinosaurs on the other side of the galaxy, Starlink space light pollution, flat or spherical universe?

The Hubble constant: a mystery that keeps getting bigger: Scientists have found a discrepancy in estimates for the rate of expansion of the universe. Why is this and what does it mean? https://www.theguardian.com/science/2019/nov/02/hubble-constant-mystery-that-keeps-getting-bigger-estimate-rate-expansion-universe-cosmology-cepheid

There’s Growing Evidence That the Universe Is Connected by Giant Structures Scientists are finding that galaxies can move with each other across huge distances, and against the predictions of basic cosmological models. The reason why could change everything we think we know about the universe. https://www.vice.com/en_us/article/zmj7pw/theres-growing-evidence-that-the-universe-is-connected-by-giant-structures
