Gravitational Observations and LQGUP

Abstract

Motivated by recent works, we employ the bounds on the dimensionless quantum-gravity parameter obtained from six gravitational tests in order to obtain bounds on the dimensionless parameter of the generalized uncertainty principle with linear and quadratic terms in momentum. The bounds obtained here are much tighter than those obtained, from the same six gravitational tests, for the dimensionless parameter of the uncertainty principle with only quadratic terms in momentum.
