Today's Lambda Cold Dark Mater (ΛCMD) cosmology model is in crisis and requires a new Kuhn paradigm. This new paradigm is presented here, analogous to shift from geocentric to a heliocentric system. All our cosmological measurements are measurements INSIDE (IN) the universe, not OUTSIDE (OUT) of space-time. This is not a trivial observation, because (IN) measurements gives a distorted picture of a simpler, true (OUT) cosmology. ΛCDM cosmology is a distorted internal view of the (OUT) spherical, linearly expanding universe using Brans-Dicke's theory generalization: Self Creating Cosmology (SCC). This (OUT) SCC model reproduces (IN) ΛCDM cosmology parameters: the ratio of matter to dark energy, the equation of the dark energy state, the time of dark energy dominance, and the value of today's acceleration. In SCC cosmology model Ωk = (-1/12), but like some cosmic “mimicry” a spherical universe “pretends” to be flat from INSIDE view. The predicted theoretical ratio of radial to transverse distance is 1.0847 for z = 1089.8, compared to experimental ratio H0(SNe)/H0(CMB) = 1.0858 ± 0.0127. This same ratio solves the S8 tension. The unexpectedly early appearance of various structures detected by JWST for large redshift is caused by incorrectly determined relation of t(z).
