This article refers to the 5th-force, which is fitting in a new model for the universe called: Rotating Torus Hologram Universe (RTHU). In this new cosmological model the lenghtscale, at which a dark boson (X17) is detected, is the 5th-force, and calculated from the perspective of how the dark matter boson affects negative-charged-quarks in the Helium-4 neutron. The lengthscale, at which X17 is detected, is theoretically calculated from formulas used in the RTHU at approximately 4,82x10^-17 meter. This relates to an Hungarian-experiment, wherein an accelerated Helium-4 atom decays in vacuum in e+ (positron) and e- (electron). Moreover, a corresponding dark energy is related to X17 and also calculated. The given exercises are based on my earlier postulated of ‘duo-bits’, which represent the dark matter force (X17), and emerges according tot he RTHU from below the non existing Planck-boundary. The RTHU in general generates materialized in-time-shifted holograms, which we experience as Big Bang universa. This is a new cosmological persepective mentioned earlier in other of my artcles.
