Description
This paper applies an emergent universal scale independent modified gravity model directly embedded in Einstein’s general relativity theory to solve the Hubble tension problem. The whole paradigm relies on an erfc potential metric whose constant offset can be assimilated to a baryonic dark energy that affects space-time measurements in the surrounding of a massive object. One key feature of this paradigm is the parameter the specific proper length that scales all the surrounding space-time of a given massive object. An observer working with the defined value for the speed of light, as it is normally done in a Mankowski inertial frame of reference, will mask the effect of the constant offset potential in the erfc metric. This results in constant gaps that introduce strong biases in numerous cosmological observations and provide new interpretations of several phenomena as observed from the Sun surrounding.
In the present talk, we focus on the Hubble Tension Problem. When an observer in the solar system is investigating light coming from distant galaxies, the difference between the defined speed of light and its predicted theoretical values is equivalent to a systematic redshift in the measurement of a given reference wavelength. Overall, this Doppler effect leads to Hubble’s Law, predicting a numerical estimate of
H0Doppler= 74.42 km/s Mpc, quite similar to the present accepted value. When the same erfc potential is associated to a source of baryonic dark energy, the Ʌ-CDM model describing the total energy available in the universe predicts a cosmic background value of H0CMB = 67.64 km/s Mpc, similar to the present accepted range of measurements. In other words the discrepancy between the is due to the fact that that has been defined at while is estimated at , the proper length of the universe. This presentation is the tip of an iceberg where numerous well accepted phenomena and challenging cosmological questions can be given a new set of coherent explanations when scrutinized under the eye of an erfc metric
