RELATIVE LOCALITY LIMIT WE STILL HAVE A DEFORMED MOMENTUM SPACE AT BUT NO WEIRD PLANCK LENGTH EFFECTS RELATED TO SPACETIME QUANTIZATION DINSTANT NONLOCALITIES - What we really see in our telescopes and particle detectors are quanta arriving at different angles with different momenta and energies. - As naive observers looking out at the world, and no less as particle physicists and astronomers, we are basically ”calorimeters” with clocks SPACETIME IS AN INFERENCE THAT WE BUILD ON MOMENTUM SPACE
CURVED MOMENTUM SPACE SPACETIME TRANSLATIONS AS THE ACTION OF TOTAL MOMENTUM ON COORDINATES WE CAN EXPRESS NONLOCALITIES AS SOME SORT OF CURVATURE OF MOMENTUM SPACE:
WORDLINES IN RELATIVE LOCALITY MOMENTUM-DEPENDENT COORDINATES
RAINBOW METRICS CAN WE FORMALIZE SUCH EFFECTS INTO A METRIC? - We notice that a pointlike observer has to perform a translation in order to study the shape of the spacetime he is in IN THE MINKOWSKIAN LIMIT FROM κ-POINCARE' MODEL WE OBTAIN:
PHENOMENOLOGY ? FOCUSING IN THE DE SITTER CASE WE CAN EASELY CALCULATE THE RATIO BETWEEN THE OBSERVED WAVELENGTH IN ALICE AND BOB:
