In recent years, the discrepancy in the value of the Hubble parameter has been
growing. Recently, there are works supporting the proposal that the uncertainty principles can
solve the Hubble tension. Motivated by this proposal, we work with an isotropic and homogeneous FRW universe, obtain its Hamiltonian equations, and thus, the Hubble parameter
through the first Friedmann equation. In the context of GUP and EUP models, the Hubble
parameter is modified. Since the fingerprints of quantum gravity are imprinted on the CMB,
we consider the GUP/EUP-modified Hubble parameter in the first Friedmann equation to be
the one measured by the Planck collaboration which uses the CMB data. The unmodified
Hubble parameter in the first Friedmann equation is considered to be the one measured by
the HST group which uses the SNeIa data. Therefore, upper bounds for the dimensionless
parameters of GUP and EUP are obtained.
