Let Prespacetime Physics Begin with the Spirit of LHC Success on March 30, 2010 (Part 1)

The Possibility for Answers from Physics (by Jonathan J. Dickau): Abstract: When considering the question of what is possible to learn in Physics, we are grappling with issues of what is known, what is unknown, and what is knowable. To an extent, this involves weeding out meaningless or misleading questions and nurturing those questions which will lead us to a greater understanding of what is happening in the universe. But often such a determination rests on finding a broad enough framework to accommodate known factors emerging from different disciplines. It is my belief that it is overly simplistic to seek ideas that reconcile Relativity and Quantum Mechanics in the form of a Quantum Gravity Theory, if what we really require is a broader framework. This paper offers thoughts on what shape that framework must have, and how we can pin down the details of its structure. Ultimately; this reveals something about the limits of what is knowable by studying Physics, and what we can learn from Science in general. http://prespacetime.com/index.php/pst/article/view/11

This Time – What a Strange Turn of Events! (by Philip E. Gibbs)

Abstract: In relativity time is bound to space by the symmetries of spacetime. In the general theory the symmetry is covariance under diffeomorphisms but in string theory this extends to the full permutation group acting on spacetime events. This huge symmetry has profound implications for the nature of time, causality and the way we see our place in the universe. http://prespacetime.com/index.php/pst/article/view/12

Two Sides of Spin Concept (by Oleg S. Kosmachev)

Abstract: The notion of the spin is shown to have two constituents, as exemplified by the spin of the electron. The first one is related to the form of the wave equation and determines the fermion or boson particle type. This implies the spin taking strictly half-integer or integer number. The second side of spin manifestation is related to the physical nature of the spin of the electron (and the corresponding magnetic moment) in the interaction resulting in nonuniform motion. It is shown that in this manifestation spin is no more fixed constant. http://prespacetime.com/index.php/pst/article/view/13

Comparison of the Algorithmic and Axiomatic Approaches to the Construction of Quantum Field Theory (by Alexander G. Kyriakos)

Abstract: Two possibilities of the quantum theory construction, indicated by Feynman, are examined. The special features of the structure of the Standard Model (SМ) are enumerated, which attest to the fact that SM is not an axiomatic, but an algorithmic theory. Deficiencies of SM and possibilities of overcoming these deficiencies are indicated. The structure of the nonlinear quantum field theory (NQFT) as an axiomatic theory, which makes it possible to overcome deficiencies in the Standard Model, is presented. http://prespacetime.com/index.php/pst/article/view/14

Is the Doubly Special Relativity Theory Necessary? (Golden G. Nyambuya)

Abstract: Giovanni Amelino-Camelia (2002) has proposed a theory whose hope (should it be confirmed by experiments) is to supersede Einstein's 1905 Special Theory of Relativity (STR). This theory is known as the Doubly Special Relativity (DSR) and it proposes a new observer-independent scale-length. At this scale, it is agreed that a particle that has reached this scale-length, has entered the Quantum Gravity regime. According to the STR, observers will, in principle, not agree on whether or not a particle has reached this length hence they will not agree as to when does a particle enter the Quantum Gravity regime. This presents the STR with a "paradox." Amongst others, the DSR is fashioned to solve this "puzzle/paradox." We argue/show here, that the STR already implies such a scale-length it is the complete embodiment of the STR, thus we are left to excogitate; Is the Doubly Special Relativity theory necessary? http://prespacetime.com/index.php/pst/article/view/9
