Description

We shall first discuss an Raychaudhury Equation Informed
Reconstruction Algorithm (REIERA) for model indepedent reconstriction of the
comiving distance from cosmological observations. Subsequently we shall define
certain characteristic redshifts where the Hubble Parameter can be directly and
accurately obtained from the comoving distances. We shall show such accurate
measurments of the Hubble parameter are in significant tensions with Planck-2018
ΛCDM predictions irrespective of early universe or late time anchors.
