Towards to Tension by the Theoretical Hubble Parameter in the Infinite Future
There exists a constant value of at when in CDM
universe with , which is independent on other cosmological
parameters. We first combine this theoretical value with the latest 43
observational data (OHD) to perform the model-independent Gaussian
Processes (GP) and constrain the Hubble constant. We obtain
=67.67, which is in agreement with
values from Plank Collaboration (2015) ( tension) but a
larger deviation from Riess et al. (2016) ( tension), while
=71.09\ tension) by
only using latest 43 OHD. Using this value, we perform
statistics with Markov Chain Monte Carlo (MCMC) method to constrain
cosmological parameters. We obtain and in flat model, and and in non-flat model, which are larger than those not using the theoretical value
