too, by postulating that locality is distributed via the fourth expanding dimension, it also provides a fundamental physical model for quantum entanglement, entropy, and time and all its arrows and assymetries. Before this post gets too long, I would like to encourage everyone to join us at: http://www.fqxi.org/community/forum/topi\\... I was on the go yesterday, so I apologize for not having time to answer your questions. Please post future questions at the new MDT forum which Anthony/FQXI was kind enough to rpovide us with: http://www.fqxi.org/community/forum/topi\\... We are having a St. Patty's party there on March 17th to celebrate our liberation from the block universe, frozen time and progress in theoretical physics, and our newfound free will. All are welcome--feel free to come and celebrate parallel universes, bouncing universes, giant voids, upcoming LHC experiments which will test string theory and probe higher dimensions, and multiverses too, but personally I stay away from the hard stuff and hangovers. Georgina--you write: "This quote is from post above Dr. E (or maybe Brian Green it isn't clear.) "Ergo the faster an object moves through space, the slower it moves through time; but all objects always move at c through the four dimensions; and light has all of its movement through space, and thus is can have none of it through the fourth dimension." If as you say all objects are moving at c along the 4th dimension. But light has all of its motion through 3D space being stationary in the 4th dimension, why is
