Where Is The Coldest Place In The Universe?
The Boomerang Nebula is the coldest place in the universe, colder even than deep space at -459°F. But why this regions of space is colder than space itself has remained a mystery to astronomers until very recently. ------------------------------------------------------ #Space #Universe #

Hidden Dimensions: Exploring Hyperspace
Extra dimensions of space—the idea that we are immersed in hyperspace—may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still--but ultimately hit a dead end. Modern

What do physicists mean by dimensions of space?
The 3 dimensions of our daily experience may be obvious, but a “dimension” means something specific to physicists. Brian Greene explains that meaning. Subscribe to our YouTube Channel for all the latest from World Science U. Visit our Website: http://www.worldscienceu.com/ Like us on Fac

Clemens Koppensteiner: T-structures from categorical actions
Abstract: T-structures on derived categories of coherent sheaves are an important tool to encode both representation-theoretic and geometric information. Unfortunately there are only a limited amount of tools available for the constructions of such t-structures. We show how certain geometr

João Lourenço: Twisted Kac-Moody groups over the integers
In geometric representation theory, one is interested in studying the geometry of affine Grassmannians of quasi-split simply-connected reductive groups. In this endeavor, one of the main techniques, introduced by Faltings in the split case, consists in constructing natural realisati
