Stringy summer cinema

This summer, as usual, there has been two major string conferences. One of them is the strings 2015, celebrated in India, and has been announced on the Lubos and Woit blog. The most relevant page of the conference contains the talks and includes links to the slides and videos to most of the conferences. I have seen some of them and my idea is to see all of the most relevant ones. Until now the one I have liked the more are the Maldacena one "Quantum mechanics and the geometry of spacetime" where he talks about the basics of black holes quantum aspects and from there he goes to his conjecture, to the correspondence ER=EPR, to the fluid-gravity duality and to some still to develop "Entanglements is the fluid mechanics of gravity" or something like that, that sounds really intriguing. Another very interesting one was the one by Ashoke Sen "Surviving in a metastable de Sitter space-time" It studies how the actual mass of the Higgs, on the metastability zone, represents a treat for the survival of the universe because there could be a transition to a most stable one in a given point and that region would grow to the speed of light. That is well known, but the new thing is that an small cosmological constant makes our universe more safe against that problem, and also discusses how having redundant information in sufficiently separated points you can be well assured against that danger. Ok, the stirngs 2015 has been announced in the blogs (although not as much as it usually was some years ago). But the thing is that recently in Madrid there was another very important string meeting String Phenomenology 2015. As with the strings 2015 there are links to the slides of the talks, and to the videos. The only difference is that instead of youtube the videos are located in another server and I am not sure for how long they will be available. The talks covers topics in string cosmology (mainly inflation). some of results and expectatives from the LHC lot of F-theory phenomenology and a few other mixed topics. Untill now I have just begun to watch the video of Eva Silverstein, that I find somewhat confuse so I can't say too much, but you can read more (in spanish) form the Francis blog El estado actual de las predicciones en teoría de cuerdas Wll, it has been really a large time that I had not written here. I hope next entry would not take that long ;-)
