An ultra-diffuse galaxy (UDG) called Dragonfly 44 was observed by the Keck II telescope, consisting mostly of dark matter. It is roughly the size of our Milky Way galaxy and certainly not fully described by the standard model of particle physics. What could such a dark galaxy be made of? Cast your votes.
It is once again time for AQG. Quantum gravity researchers invade the silicon valley. The synthesis will be quite potent. From Tannakian categories and motivic L-functions, to Shimura Varieties and exceptional gradings, let the games begin.
Beginning next week, Advances in Quantum Gravity 2015 (AQG 2015) will begin. Some of the most innovative young theorists in the world will gather to discuss the latest research in quantum gravity and unified field theory. The conference is invitation only, with participants sharing the latest ideas from all major approaches to quantum gravity, in a formalism independent setting.
At a conference in Stockholm, famed physicist Stephen Hawking explains how he thinks information is stored in black holes - it is stored as supertranslations of the black hole event horizons. (KTH Royal Institute of Technology)
