Hello Jets Big and Small maybe the key to understanding the universe. On a side issue from the Quasars and cosmology post, since the file is locked. Response to Neried I understand your logic, your good. But! You said I'm quite awear of the huge and upto date papers on quasars, so called black holes, degenerate matter, jet formation etc. As for the unified AGN model, if History proves me write, unification is only temporary if that. As for Jets Big and Small http://arxiv.org/abs/0812.0021 Gamma-ray Burst 080319B: Evidence for Relativistic Turbulence, Not Internal Shocks Authors: Pawan Kumar, Ramesh Narayan (Submitted on 1 Dec 2008) The question that most ask is where and how does the jet form. The properties of jets are studied in depth and as time passes our abilty to study them in depth increases. Its fun and games for the next few years.
