  Recently much controversy has been raised about the cosmological conundrum
involving the discrepancy in the value of the Hubble constant as implied by
Planck satellite observations of the CMBR in the early Universe and that
deduced from other distance indicators (for instance using standard candles
like supernovae, tip of the Red Giant branch, etc.) in the present epoch. The
Planck estimate is about 67 km/s/Mpc, while that deduced from distance
indicators at the present epoch is around 73-74 km/s/Mpc. Also the independent
determination of the local value of the Hubble constant based on a calibration
of the Tip of the Red Giant Branch (TRGB) and applied to Type Ia supernovae
found a value of 69.8 km/s/Mpc. Here we propose a modification of the
gravitational field on large scales as an alternate explanation for this
discrepancy in the value of the Hubble constant as implied in the
above-mentioned method, i.e., by Planck observations of the CMBR in the early
Universe and that deduced from other distance indicators in the present epoch.
