Relative Spacetime Transformations in Gamma-Ray Bursts

GRB 991216 and its relevant data acquired from the BATSE and
the Rossi X-Ray Timing Explorer and Chandra satellites are used
as a prototypical case to test the theory linking the origin of
gamma-ray bursts (GRBs) to the process of vacuum polarization
occurring during the formation phase of a black hole endowed with
electromagnetic structure. The relative spacetime transformation
paradigm is presented. It relates the observed signals of GRBs to their
past light cones, defining the events on the worldline of the source that
is essential for the interpretation of the data. Since GRBs present regimes
with unprecedentedly large Lorentz factors, and also sharply varying with time,
particular attention is given to the constitutive equations relating the four time
variables: the comoving time, the laboratory time, the arrival time, and the arrival
time at the detector corrected by the cosmological effects. This paradigm is at
the very foundation of any possible interpretation of the data of GRBs.
