Star Wars Technical Commentaries, or SWTC, are a set of detailed documents exploring the nature and limits of the technology of the Star Wars universe. They are maintained by Curtis Saxton, Ph.D. (Astrophysics) and located at TheForce.net. His work is solely interested in establishing the limits and characteristics of Star Wars technology. Some topics brought up are the Endor Holocaust, firepower of the Death Star, actual sizes and different models of Super Star Destroyers and many other things.
His methodical and empirical methodology has proven controversial amongst fans, and is reportedly disfavored by some at Lucasfilm (notably Pablo Hidalgo) who would prefer a less scientific view of the Star Wars franchise.
