Conformal Transition from an Asymptotic Massless Phase as the Origin of the Hot Big Bang An Effective Model with Interpretation of Cosmological Infinity and Asymptotic Evolution

This work presents an effective cosmological model in which the Hot Big Bang is interpreted as a conformal transition from an asymptotic massless phase of the Universe preceding the observable cosmic epoch. The model introduces a scalar field φ serving as a conformal field and a dynamical mechanism for the suppression of Weyl curvature, leading to conformal flatness of spacetime.The conformal boundary is described by asymptotic conditions:φ → 0Cμνρσ → 0which signify the disappearance of conformal inhomogeneities in the geometry.The causal structure of spacetime remains preserved because light cones – introduced in the spacetime formalism by Hermann Minkowski – are invariant under conformal transformations.In this interpretation the Big Bang is not a geometric singularity but a phase transition between successive cosmic epochs.The model is extended to include a scenario of the asymptotic future of the Universe and an interpretation of infinity as a sequence of cosmic phases.
